In this Filed Test Shooting Video recorded in the Replica Airguns Indoor Sea Can Shooting Range, I test out the Gamo GP-20 Combat CO2 BB Pistol to see what the actual velocity is in fps shooting 4.5mm steel BB’s with a fresh CO2 Cartridge. I also shoot 10 rounds of BB’s into a paper target setup 30 feet down range to see just how accurate the accurate the Gamo GP-20 Combat Pistol is out of the box. If you are more interested in details and specifications along with some closer up video of the Gamo GP-20 Combat CO2 BB Pistol, then make sure to watch my Table Top Video for it located here.
So let’s get to the velocity test for the Gamo GP-20 Combat CO2 BB Pistol. Gamo does claim up to 400 fps and to find out if these claims are true, I first installed a brand new 12 gram CO2 cartridge in the Gamo GP-20 Combat CO2 BB Pistol and proceeded to shoot 5 rounds through my Chronograph. I then averaged the shots out and was impressed with a much higher than claimed velocity of 422 fps. My slowest recorded shot was 419 fps with the fastest shot hitting 424 fps, so all of them very close to each other.
Moving on to the accuracy portion of my Field Test, I then setup a brand new paper target 30 feet away and using a semi rested shooting position (Hands on a sand bag up front and sitting on a stool in the back), I purposely shot 10 rounds with care into the target. The Gamo GP-20 Combat CO2 BB Pistol does not have adjustable sights at all so you will have to adjust your aim point if it is not bang on out of the box for you. That said, for me I was able to get about a 3 inch 10 round shot grouping, fairly well centered but just a bit to the left, about an inch or so. The shots did spread out a bit more up and down with less of a spread left to right, but still a decent grouping none the less.
The Gamo GP-20 Combat CO2 BB Pistol is like many of these low cost CO2 NBB BB Pistols, was very predictable as I have shot a ton of them and since they all share similar mechanical attributes internally, they tend to shoot about the same. I don’t mean this as a bad thing since they generally all shoot fairly decent with right around 400 fps velocities and generally I get anywhere from a 2 inch to 4 inch grouping with them. The good parts is the design is tried and trued and seems to be very durable and problem free with less moving parts to go wrong. They are also rather low cost and the magazines are interchangeable, so if you have other models based on this same build design, then you can mix and mach your magazines and load them all up for non-stop shooting fun. I do like the overall feel of this NBB CO2 BB Pistol, and the sights are very easy to aim with being white dot in the front and fiber optic in the back. If you are looking for a low cost basic NBB CO2 BB Shooter then this could just check all those boxes for you.
Another box showed up at my door and this time I had no idea what was inside it, I asked the boys in the warehouse to surprise me and send some new product as I was low on review items, and in a couple of days later this tall somewhat large box showed up. In this Replica Airguns June Mystery Box Unboxing Video I open the box and take a look at what’s inside. I recommend you just watch the video and enjoy the suspense with me, but if you want to cheat and find out now, then look below at quick breakdown of each item…
In this Filed Test Shooting Video recorded in the Replica Airguns Indoor Sea Can Shooting Range, I test out the GAMO P-27 NBB CO2 Dual Ammo Pistol to find out what the actual velocity is in fps shooting both 4.5mm steel BB’s and .177 caliber lead Pellets. I also put a full side of each magazine into a paper target setup 30 feet down range again using both BB’s and Pellets to see which ammo type may be more accurate out of the GAMO P-27 NBB CO2 Dual Ammo Pistol? If you are more interested in details and specifications along with some closer up video of the GAMO P-27 then make sure to watch my Table Top Video for it.
Let’s get right to the velocity test of the GAMO P-27 NBB CO2 Dual Ammo Shooting 4.5mm Pistol. Gamo does claim up to 430 fps, I am not sure if this is for BB’s or Pellets or maybe even light weight alloy Pellets. In any case I used standard 4.5mm 5.1 grain steel BB’s and around 7 grain lead Pellets for this test. Shooting 3 rounds of 4.5mm steel BB’s through my Chronograph I averaged 342 fps with the three shots recording 349, 342, 334 fps. Switching to lead Pellets I averaged 288 fps with the three recorded shots of 290, 291, 282. The 4.5mm steel BB’s as you can see shot faster than the lead Pellets but this was most likely due to the heavier weight of the lead pellets.
I was interested to find out if the .177 caliber Pellets where going to be more accurate in the GAMO P-27 NBB CO2 Dual Ammo Pistol as pellets traditionally are more accurate than BB’s but in the case of the GAMO P-27 the barrel is not rifled so there may be less of a benefit shooting pellets for accuracy purposes? The best way to find out is to try it out so that’s exactly what I did. Again starting with 4.5mm steel BB’s I place one side of the 16 round magazine, so 8 rounds into a fresh pepper target setup 30 feet away. I did use my standard shooting stance of sitting in the back on a stool and placing my hands on a sand bag up front for some stability. I did notice the GAMO P-27 NBB CO2 Dual Ammo Pistol liked to shoot a bit high and to the left but I did get around a 3.5 inch grouping and if I removed two shots that where on the outside of the grouping I would have had closer to a 2 inch grouping. Switching to the .177 caliber Pellet side of the magazine I then was able to get my 8 rounds a bit tighter hitting around a 1.5 inch grouping with most of the shots all within 1 inch of each other. Pellets at least for me where the better choice in terms of accuracy.
The GAMO P-27 NBB CO2 Dual Ammo Pistol is a fun little BB and Pellet plinker capable of plinking and action shooting at closer up ranges. I would not want to shoot out much further than 30-40 feet or so but it is accurate enough especially with Pellets to hit pop can sized objects at those ranges. I do like that you have the option of shooting both single and double action as the GAMO P-27 NBB CO2 Dual Ammo Pistol does have an actual working hammer and this does lighten up the trigger a bit more for accurate shot placement when shooting in single action. If a fairly affordable NBB dual Ammo Airgun is what you are after than consider grabbing yourself one over at of one of our Replica Airgun Online Stores, Canada or the US.
Type: NBB CO2 BB Pistol - Pellet Pistol. Manufacturer: Distributed by Gamo. Model: P-27. Materials: Plastic & metal. Weight: 1.5 pounds (681 grams). Total Length: 7 inches (178mm) Barrel: 3.75 inches (95mmm) metal non-rifled. Propulsion: CO2 x 1. Action: Semi auto NBB, single and double action trigger. AmmunitionType: 4.5mm steel BB's - .177 Cal. Pellets. AmmunitionCapacity: 16 round (8x8) drop out plastic stick magazine. FPS: Claimed 430.
Trigger Pull: The trigger pull on the GAMO P-27 NBB CO2 Dual Ammo Pistol is fairly good considering there is no blowback action to pre-cock the hammer. In Single action you can manually cock the hammer for a somewhat lighter trigger pull or you can simply pull the trigger in double action mode which cocks the hammer and cycles the rotary magazine. Both shooting modes are about the same trigger length as the first part of the trigger pull advances the rotary magazine and even in double action the trigger is fairly light but not as light as a true single action trigger.
Accuracy: At this point I have not tested or shot the GAMO P-27 NBB CO2 Dual Ammo Pistol but I do plan on making a Field Test Shooting Video as soon as I can which may be a few weeks as I am attending SHOT Show 2024 next week which will be the focus of my attention for the next few weeks. All I can go on is what Gamo claimed which is an fps of 430 using light weight pellets. When I make my Field Test Shooting Video for the GAMO P-27 I will test it out with regular lead pellets and Steel BB’s.
Build Quality: The build quality of the GAMO P-27 NBB CO2 Dual Ammo Pistol is good overall. Yes it does have a pretty much full plastic shell, but there is enough metal inside to give it a decent 1.5 pound weight which for a smaller pistol like this makes it feel solid in the hand. There is no blowback action which reduces the amount of moving mechanical parts which will make the GAMO P-27 less prone to wear and possible malfunction so I would expect it to be reliable for a long time.
Realism: The GAMO P-27 NBB CO2 Dual Ammo Pistol as far as I can tell is not an exact copy of a real steel pistol in production but it does look like a real gun for sure. It does have a working safety on the slide which is not your typical low cost airgun switch and the barrel is slightly recessed. The CO2 tab is also hidden fairly well at least when looking from the side, so unless you get close to the pistol you would think it was real for sure. That said some giveaways would be the moulded into the slide ejection port and the screw holes on the right side of the two plastic halves of the airgun, but again close inspection would only really reveal this .
Pros:
Has a good weight and feel to it, not cheap feeling in the hand.
Can shoot both BB’s and Pellets.
Has a single and double action trigger/hammer.
Uses standard Gamo/Umarex double sided rotary magazines.
White dot sights for easy sight acquisition.
Realistic safety lever on the side of the slide.
Picatinny rail for add on accessories.
Recessed barrel adds to realism.
Claimed decent high velocity of 430fps.
Cons:
Mostly plastic external gun.
Sights are fixed so no adjustment.
No blowback action if that is important to you.
Comments:
As far as I can remember, I have not seen an Airgun that uses this type of double sided rotary magazine that has not had blowback operation so it will be interesting to see how it shoots. I do expect it to be a bit more powerful than its Blowback counterparts. Overall the GAMO P-27 NBB CO2 Dual Ammo Pistol is well built and solid and looks to have a good trigger on it for either double action quick paced shooting or more slowed down accurate shooting in single action. I will for sure be testing it using both BB’s and Pellets, but I have a feeling both will shoot similarly at the end of the day since the barrel is not rifled giving the pellets less of an advantage.
Starting the year off with a Preview Unboxing Update Video of three CO2 Air Pistols. One from Gamo is a NBB CO2 Dual Ammo (Pellet/BB) Semi Auto style pistol called the Gamo P-27. The other two are for Crosman and are both Revolvers but from very different aras. The First Revolver I look at is the Crosman SNR357 which is essentially an early revision rebranded Dan Wesson in a 2.5 inch barrel. You can use either .177 caliber pellets or 4.5mm BB’s with it loading them into the 6 shells that come with it. A new comer I have never seen is the Crosman Fortify styled after the classic Single Action Army Colt 45 old West Revolver. Unlike many of today shell loading CO2 Revolvers, the Crosman Fortify has an internal tube fed magazine with a spring follower that holds 18 4.5mm Steel BB’s.
Watch my Preview Unboxing Update Video where I take a quick look and go over some basic specifications along with my initial thoughts…
As always I placed a brand new C02 in the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol to get maximum power and the temperature was around 21 degrees Celsius or about 70 degrees Fahrenheit which is warm enough to get good velocity results but not hot enough for maximum fps so keep that in mond. I deiced to shoot 4 Steel BB’s, and 4 Lead Pellets through my chronograph and averaged the velocities out for each ammo type. The Steel BB’s weigh about 5.1 grain while the Lead Pellets weigh a bit over 7 grain so I was expecting to see higher numbers with the BB’s which is exactly what I got but not near as high as the claimed 495 fps.
My actual velocity result for Lead Pellets was a 4 shot average of 332 fps with the slowest being 313 and the fastest shot hitting 359. For steel BB’s I was able to average 346 fps so not a lot faster at the end of the day but close. My slowest Steel BB Chronograph reading was 342 with the fastest shot at 356 which was actually just a bit slower than the Lead Pellet fastest velocity reading. Lead Pellets tend to seal in the barrel better than Steel BB’s so even though they are a bit heavier they still get pretty close velocity readings to BB’s since the less CO2 blows by the ammo with Lead Pellets.
Sine the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol has a double sided rotary magazine that holds 8 rounds on each end, I loaded one side with BB’s and one side with Pellets and proceeded to see how tight of a grouping each ammo type was capable of with 8 rounds. As expected again the Lead Pellets performed better getting about a 1.5 inch grouping well centered up a down on the bullseye but a tad to the left of it. The Steel BB’s did spread out somewhat getting closer to a 4 inch grouping that this time was better centered side to side but a little bit low of the Bullseye. Out of the box the sights seem to be fairly well centered which is nice since they are not adjustable.
So the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol isn’t the flashiest Replica Airgun out there, maybe not the most powerful or accurate Airgun either but it is fun to shoot and does offer more options in terms of ammo choices when shooting. Velocity is really close between Steel BB’s and Lead Pellets and since the Lead Pellets are about 2 grain heavier they will have more energy downrange when they hit a target. The Lead Pellets also performed better in the accuracy department and shot a respectable 1.5 inch 8 shot grouping so if this was my Airgun I would probably go with Lead Pellets as long as I had some on hand, but if all you have around is Steel BB’s than at least you can keep on shooting which is what it’s really about at the end of the day.
Type: Non-blowback CO2 BB and Pellet Pistol. Manufacturer: Distributed by Gamo. Model:P-430. Materials: Mostly plastic. Weight: .94 pounds (427 grams). Total Length: 8 inches (203mm). Barrel: 4.75 inches (121mm) metal non-rifled. Propulsion: CO2 x 1. Action: Semi auto non-blowback, DOA trigger. Ammunition Type: .4.5mm steel BB’s and .177 caliber pellets. Ammunition Capacity: 16 round drop out plastic stick magazine. FPS: Claimed 495.
Trigger Pull: The Gamo P-430 CO2 Dual Ammo BB Pellet Pistol is typical of a double action tiger in that it is a longer trigger pull that requires more effort to pull. The Gamo P-430 trigger is I would say good for a DOA trigger as it is not overly heavy and does allow for fairly quick rapid fire shooting. The trigger pull not only cocks the hammer, it also rotates the rotary magazine on either end of the stick magazine so there is a lot going on here but it still is not overly heavy which is nice.
Accuracy: I have yet to shoot the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol or performed my standard Field Test shooting Video so I can not comment at this time on the performance other than what is claimed in terms of fps. Which if accurate will be one of the more powerful CO2 BB/Pellet guns, but we will see when I do my Field Test Shooting video. Accuracy is not claimed so hopefully the accuracy out of the box is as good as the claimed fps…
Build Quality: The Gamo P-430 CO2 Dual Ammo BB Pellet Pistol is a pretty much all plastic Airgun with only a few metal parts I can make out. The trigger is metal along with the inner barrel and the area where the CO2 goes in. Because of the plastic build, it is fairly light weight which can actually be good in a fall as the mass is low resulting in less damage if you were to drop it on a hard surface. Scratches will also be less noticeable on a plastic Airgun over a metal Airgun as the material on a plastic Airgun is all black rather than a painted surface that will show blemishes a lot more. The simplicity of the design means you should get a lot of shots from the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol before encountering any problems.
Realism: The Gamo P-430 CO2 Dual Ammo BB Pellet Pistol is not a replica of a specific real steel gun in production but it does share a lot of cosmetic characteristics as a Sig Sauer Pistol such as the M17 and P226. There are few external mechanical working parts on the Gamo P-430 other than the trigger, safety and magazine release and as mentioned already the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol is rather light weigth which takes away from the realism. The barrel is slightly recessed and the CO2 tab is hidden in the grip which helps in terms of realism.
Pros:
Claimed high velocity of 495 fps.
Expect lots of shots per CO2 as compared to a blowback Airgun.
Simple design means it will have less to go wrong over time.
Picatinny rail for add on accessories.
Can use either 4.5mm Steel BB’s or .177 caliber pellets.
Cross bolt safety to prevent accidental shots.
Has a Sig Sauer like look to it which is a good thing.
Double ended stick magazine works well and does not add too much friction to the trigger pull.
Well hidden CO2 Screw, no tools required.
Fit and warning instructions on Airgun is embossed and color matched so it is very subtle.
Cons:
Mostly all plastic Build.
No white dot sights so will be harder to see on darker backgrounds, also not adjustable.
Light weight with no blowback action so not as good realism and a cheaper feel to it.
Trigger is a bit long but not crazy heavy.
Comments:
I personally prefer blowback Airguns that have a more solid weight and feel to them, but again there is a lot more that can go wrong and parts tend to wear out over usage a lot quicker than a more simple design like in the case of the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol. Price is also going to be a lot less when looking at the Gamo P-430 as the plastic build is a lot cheaper to produce. On the other hand these non-blowback CO2 airguns do tend to have a much higher velocity and also generally you will also get more shots per CO2 than a similar CO2 Blowback Pistol so you have to give to get, it really depends what features you want more and in this case you also get a more cost effective Air Pistol with plenty of shooting enjoyment.
In this Update Preview Video I take a look at three CO2 Air Pistols from ASG, Gamo and Barra. All shoot 4.5mm steel BB’s and one can also shoot .177 caliber pellets. two of them have blowback action. Two are also styled after the popular 1911 Semi Auto Pistol. The ASG 1911 has a unique magazine and chambering system that is the first I have seen of this in a Blowback Airgun. It offers with blowback operation along higher fps and a nice light semi auto trigger, which is a combination not offered in many Airguns.
Type: Pellet Revolver. Manufacturer: Gamo Model:PR-776. Materials: Mostly metal construction. Weight: 2.2 Pounds (1 kg). Barrel Length: 6 inches Total Length: 11.5 inches. Propulsion: CO2 x1 Action: Revolver single and double action. Ammunition Type: .177 caliber pellets. Ammunition Capacity: 8 rounds per magazine. Max FPS: 400+ fps.
Trigger Pull: The Gamo PR-776 CO2 .177 Caliber Pellet Revolver has your traditional revolver single and double action trigger setup. In double action, the trigger is going to be a bit longer and heavier but it feel fairly smooth with no real friction points and I would consider it to have a medium trigger pull. When you cock the hammer back placing the Gamo PR-776 CO2 .177 Caliber Pellet Revolver in single action, the trigger pull becomes very short with virtually no take-up at all and the weight of the trigger is very light allowing for more accurate shots.
Accuracy: Make sure to watch my Field Test Shooting video for the Gamo PR-776 CO2 .177 Caliber Pellet Revolver where I test out the velocity and accuracy in the Replica Airguns Indoor Airgun Shooting Range. In summary the Gamo PR-776 CO2 .177 Caliber Pellet Revolver shot a little bit hotter than claimed at just over 400 fps using around 7 grain lead pellets. In terms of accuracy with a total of 16 shots the grouping spread out to around 4 inches but I am pretty sure a different pellet choice may have made a difference.
Build Quality: The build quality of the Gamo PR-776 CO2 .177 Caliber Pellet Revolver is pretty good overall. It is mostly all metal with the exception of the grips of course, Fit and finishes looks good, everything feel snug adn tight with the exception of the pistol grips. I feel like the grips could easily move out of place and get caught on something. This is not a problem when shooting, more so when in a holster. The Gamo PR-776 CO2 .177 Caliber Pellet Revolver feels good in the hadn't, nice and solid and with a good weight to it.
Realism: The Gamo PR-776 CO2 .177 Caliber Pellet Revolver is a decent looking Airgun in the style of a traditional revolver, I wouldn’t say it’s an exact replica of any specific revolver in production but it does tick off all the boxes in terms of looking realistic. The weight and feel for now and the Gamo PR-776 CO2 .177 Caliber Pellet Revolver also has a recessed barrel and hidden CO2 crew. The only real giveaway would be the cylinder size as it is a bit smaller than expected and of course is chambered for .177 caliber pellets.
Pros:
Good power over 400 fps using actual lead pellets.
Quicker reloading over shell loading revolvers
More shots per magazine reload, 8 versus 6.
Comes with two metal 8 round magazines.
Traditional single and double action trigger.
White dot front sight with fully adjustable rear sight.
Good weight and feel to it.
Fit and finish look good.
Recessed barrel for realistic looking barrel opening.
Should be able to use a dovetail type scope mount for adding on a red dot or magnified scope.
Cons:
Not a fan of the loose pistol grip setup to access the CO2.
Was hoping to get a bit tighter grouping but may have been a pellet choice issue.
Comments: It was nice reviewing the Gamo PR-776 CO2 .177 Caliber Pellet Revolver as it was a bit different then most of today shell loading revolvers. I like that the Gamo PR-776 CO2 .177 Caliber Pellet Revolver still offered a realistic looking cylinder that the shell loading revolvers have but with the moon clip style magazines that allow for quick adn easy reloading of 8 rounds at a time. The velocity or power of the Gamo PR-776 CO2 .177 Caliber Pellet Revolver was even a bit high than Gamo claims using PBA Platinum pellets since Gamo claims 400 fps using these 5.1 grain lead pellets. My testing with closer to 7 grain pellets yielded fps up and over 400 fps. All the Gamo PR-776 CO2 .177 Caliber Pellet Revolver needs is to be just a little bit more accurate but I feel this may simply be more of a pallet choice, once you find a pellet the Gamo PR-776 CO2 .177 Caliber Pellet Revolver likes I am pretty sure it will deliver accurate shots.
My Table Top Review for the Gamo PR-776 CO2 .177 Caliber Pellet Revolver:
Make sure to watch my upcoming Table Top Review for the Gamo PR-776 CO2 .177 Caliber Pellet Revolver where I go over the specifications, pros and cons and show it up nice and close. In this Field Test Shooting Video I determine what the accuracy and velocity of the Gamo PR-776 CO2 .177 Caliber Pellet Revolver by testing out the fps with my Chronograph along with a accuracy test shooting a paper target at a distance of 30 feet away using a rested shooting position.
For the velocity test I placed a brand new CO2 Cartridge in the Gamo PR-776 CO2 .177 Caliber Pellet Revolver and shot five 6.9 grain lead pellets though my Chronograph. Gamo claims their 5.1 grain PBA Platinum pellets will shoot around 400 fps so I was expecting something in the low to mid 300’s but was surprised at a five shot average of 4115 fps with the much heavier RWS6.9 grain pellets. The slowest shot I achieved was 396 fps while the fastest shot was 434 fps. The temperature was right around 24 degrees Celsius or 75 degrees Fahrenheit.
For the next section of my Field Test Shooting Review I setup a brand new paper target 30 feet down range and loaded up two eight round magazines. The results for the Gamo PR-776 CO2 .177 Caliber Pellet Revolver where a bit confusing with both eight round magazines. It seemed like most of the shots wanted to group within about 1-2 inches of each other but I was getting several outliers that extended the grouping to closer to four inches. Not the best performance but as I have found with many guns, sometimes you need to find a pellet that the gun is happy with. the wrong pellet can really make a difference and I am fairly sure this was the case with the Gamo PR-776 CO2 .177 Caliber Pellet Revolver using the RWS pellets. just not the best choice for it.
The Gamo PR-776 CO2 .177 Caliber Pellet Revolver overall performer well, like I said I really think pellet choice will be the deciding factor in how accurate it is going to be. The velocity was very good for a CO2 Pellet revolver considering I was suing actual lead pellets and not the alloy pellets Gamo was using as their reference. The Gamo PR-776 CO2 .177 Caliber Pellet Revolver uses metal eight round magazines which are easy to preload and allow for two additional shots over the more common these days shell loading revolvers, which makes the Gamo PR-776 CO2 .177 Caliber Pellet Revolver more practical as a target pistol allowing for more power and easier loading.
Type: Break Barrel Pellet Pistol. Manufacturer: Gamo Model:P900 IGT. Materials: Mostly plastic build with some internal metal parts. Weight: 1.28 Pounds (580 grams). Barrel Length: 6.25 inches Total Length: 12.52 inches. Propulsion: Gas Piston (IGT) Action: Break barrel single action trigger. Ammunition Type: .177 caliber pellets.. Ammunition Capacity: 1 round. Max FPS: 400 fps using PBA Platinum pellets (about 5 grain).
Trigger Pull: The trigger on the Gamo P900 IGT .177 Caliber Pellet Pistol uses what Gamo calls their SAT or Smooth Action Trigger system. Overall the single action only trigger feels pretty good, not super light but also not overly heavy. The Gamo P900 IGT .177 Caliber Pellet Pistol has a short take up with a very predictable release point. I found it fairly easy to use and shoot with precision.
Build Quality: The Gamo P900 IGT .177 Caliber Pellet Pistol is mainly made out of plastic, pretty much everything is plastic including the trigger but there will be internal metal parts where they are required. That said the Gamo P900 IGT .177 Caliber Pellet Pistol feels well made with fairly heavy plastic throughout. The Gamo P900 IGT .177 Caliber Pellet Pistol is not super heavy but feels hefty enough in the hand.
Realism: The Gamo P900 IGT .177 Caliber Pellet Pistol is not a replica of any specific pistol in production and has a very modern look to it. I would say it looks more like an airgun than a real gun and that’s exactly what is’t supposed to be so this is not a negative in this case.
Pros:
Reasonable price for a target pistol.
Performed well, can easily get .5 inch groupings from 30 feet away.
No need for CO2.
Inert Gas Technology (IGT) has less vibration and no reduction to power over time.
Fiber optic front sight.
Adjustable rear sight for windage.
Inexpensive to shoot.
Made in Spain.
Ambidextrous design.
Reasonable trigger pull.
Cons:
Not supper powerful. Shot around 300 fps with standard lead pellets.
A bit hard to cock because of such a short barrel.
Rear sight is only adjustable for windage and not elevation.
Comments: The Gamo P900 IGT .177 Caliber Pellet Pistol is a nice overall low cost target pistol with a very modern look and Gas Piston technology. In terms of performance the Gamo P900 IGT .177 Caliber Pellet Pistol tested well for me shooting accurately with a consistent 300 fps velocity which is what you want in a target pistol, consistency over raw power. I like the overall design and look, the Gamo P900 IGT .177 Caliber Pellet Pistol feels good in the hand and easy to shoot, the trigger is not overly light but is also not too heavy by any means. My only complaint is the cocking effort involved because of such a short barrel and I also noticed a bit of a stickiness with the cocking effort but I have a feeling this may break in over time or perhaps a drop of oil in the hinge area may do the trick. If you want a modern looking target pellet pistol with good performance than the Gamo P900 IGT .177 Caliber Pellet Pistol will for sure fit the bill!
My Table Top Review for the Gamo P900 IGT .177 Caliber Pellet Pistol:
For this Field Test Shooting Video Review of the Gamo P900 IGT .177 Caliber Pellet Pistol I test the power and accuracy to determine what the real world (fps) Feet Per Second velocity and how tight of a grouping I can get for 30 feet down range.
For the power portion of my Indoor Filed Test I shot five RWS 6.9 grain lead pellets through my Chronograph with an average velocity of 305 fps. This resulted in a 1.43 foot pound energy rating. My slowest shot out of the Gamo P900 IGT .177 Caliber Pellet Pistol was 289 fps and the fastest shot was 311 fps. Gamo claims the Gamo P900 IGT .177 Caliber Pellet Pistol can achieve 400 fps but this would be using lighter alloy pellets like PBA Platinum pellets.
Next I setup at a fresh paper target 30 feet down range and proceeded to place 8 shots into the target using a seated and rested shooting position. My first shot was a bit high as I was getting use to the trigger but the following 7 shots all grouped within about 3/4 of an inch, 6 of them all within a half inch of each other so the Gamo P900 IGT .177 Caliber Pellet Pistol is for sure capable of 1/5 inch groupings from a 30 foot distance. The placement of the shots grouping was a little bit high and to the left. since the Gamo P900 IGT .177 Caliber Pellet Pistol has an adjustable trigger for windage I could easily center the grouping right in the middle. In terms of elevation there is no adjustment so I would need to manually adjust this on the fly depending on the distance I was shooting at.
The Gamo P900 IGT .177 Caliber Pellet Pistol performed very well for me, the power is what you would expect for a target pistol, I would not recommend the Gamo P900 IGT .177 Caliber Pellet Pistol for any pest control. Accuracy was very good and I feel once getting use to the trigger you shoudl be able to get shots all within a 1/2 inch at 30 feet. The trigger is not super light but by no means is it heavy, the take-up is short with a predictable release, I found the trigger to work well overall. My only complaint is cocking the Gas Spring as the barrel is short and it does take some effort to do this, especially getting it started off, once you get past the first little bit it does get easier to cock. If you’re looking for a nice accurate target pellet pistol at a relatively inexpensive price point then for sure consider the Gamo P900 IGT .177 Caliber Pellet Pistol.
Make sure to watch my Vimeo video for this Comparison Review as I go into a lot of detail about the similarities and difference with each of these CO2 Blowback Pellet Guns.
All of these CO2 blowback pellet guns are made for each company in Japan (I am assuming from the same factory?)
All of the listed Pellet Airguns shoot .177 caliber pellets (Can be Alloy or Lead)
They all have double sided rotary stick magazines that hold 8 rounds on each end for a total of 16 shots per magazine.
All of the Airguns use 12 gram CO2.
All compared pellet guns have Blowback operation.
All of these pellet pistols have single and double action triggers except for the Gamo MP9 which is single action only and needs to be charged on the first shot.
They all have rifled barrels.
Here is where we find some key differences between these CO2 Blowback Pellet Pistols:
Installment number 2 of my Head-to-Head Airgun comparisons. In this video I compare the replica Umarex Beretta PX4 Storm CO2 Blowback Pellet Pistol versus the Gamo PT-85 CO2 Blowback Pellet Pistol. Both are very similar mechanically and use very similar rotary magazines combined with single action hammers and very heavy blowback.
Watch the video below to see the Beretta PX4 Storm CO2 Blowback Pellet Pistol go head to head against the Gamo PT-85 CO2 Blowback Pellet Pistol in both a test of the feet per second performance and accuracy shooting at 30 feet using a semi rested position.
I get many question over on my Vimeo Channel, lots of times people asking me which gun is better and in most cases it really comes down to personal preference. But in some situations the comparisons are really close and to be honest it's even hard for me to decide which gun I think is better.
I get asked which one has higher fps, or is more accurate, or has harder blowback recoil... the list goes on. Without actually taking both gun outside and doing a head to head test using the same exact situations, I really can not honestly tell you! So that's exactly what I am going to do. Take some of the most commonly asked about gun comparisons and have a showdown.
Over the next while I will be making a total of five separate videos where I compare the following CO2 BB pistols head to head:
After posting my Table Top Review for the Gamo MP9 Blowback CO2 Pellet and BB Tactical Airgun, It seemed like most people where pretty interested with it and where looking forward to my Field Test Shooting Review. So I wanted to get this one out before the Holidays! Thought I would wear my Santa hat for this one :)
I did manage to get my Chronograph problem figured out so for this test I got reads on all 8 shots which was awesome! So how did my Gamo MP9 Blowback CO2 Pellet and BB Tactical Pistol perform? Pretty nicely overall, since it has 8 shots at each end of teh 16 shot rotary magazine I decided to base my testing on 8 shot groups. The first 8 shots where aimed through my Chronograph resulting in an average 415 fps using 7 grain RWS lead pellets. Not bad considering how cold it was and the fact that I was not using the super light weight PBA® Platinum Pellets. I would expect even lead pellets to hit 450 fps on a warm day.
The next 8 rounds where designated for the paper target which was setup 30 feet from my semi rested position (rested on sand bag and standing in the back). All 8 rounds shot within 1.5 inches and I am pretty sure I could do this all day long with this pellet shooter. I then emptied the other half o my magazine on my swinging steel targets and it appears I hit them most of the time looking back on my video.
The blowback is minimal with this CO2 blowback pistol, I don't think the internal blowback mechanism caries that much weight to it but you do feel some blowback when the CO2 is new and full. Gamo claims the trigger to be around 9.5 pounds worth of pull but to me it feel much lighter, combine that with the pull length being fairly short and you can shoot 8 rounds off at a time in a hurry with this Gamo MP9 Blowback CO2 Pellet and BB Tactical Airgun.
If I could have my way I would have liked to have seen a working ejection port like the Umarex MP5K PDW and perhaps a bit more blowback feel but other than that the Gamo MP9 Blowback CO2 Pellet and BB Tactical Pistol is a great replica CO2 Blowback pellets gun for the money.
Ammunition Capacity: 16 shot drop out double sided magazine.
FPS: 450 (with Gamo's PBA® Platinum Pellets.)
Trigger Pull: The trigger pull for the Gamo MP9 Blowback CO2 Pellet and BB Tactical Airgun is stated to be a single and double action trigger which is kind of true and false at the same time. Yes you can pull the charging handle back which does pull the internal hammer back for a single action hammer release but you can not shoot this pistol in double action only unless the charging hammer has been pulled back technically making the Gamo MP9 a single action only pistol? On the other hand, even with the hammer back, the trigger has to rotate the pellet magazine with each shot making it a double action only trigger? So what is it really, kind of both and kind of neither? Well who really cares about all that... In the end the trigger even though stated to be around 9.5 pounds of pull feels much lighter than that 9.5 pounds and has a pretty short action so shooting this gun rapid-fire is pretty easy and not too tiring on the finger. Another bonus is that the trigger safety also works, it's not just for show!
Accuracy: I will be following this table top review with a full field test shooting review shortly but I did have the chance to take my Gamo MP9 Blowback CO2 Pellet and BB Tactical Airgun out for a test drive so I would be able to give you some of my initial shooting feedback. I started off with a full CO2 using RWS 7 grain flathead lead pellets and placed a full 8 shots through my Chronograph, the first 4 shot a bit over 400 fps with the fastest shot being right around 430 fps, the last 4 shot a bit under 400 fps with the slowest shot hitting around 370 fps. Since it is December the weather outside was a bit frosty ;) so I would expect to get most shots in or above 400 fps in warmer weather. Moving on to some target results, my main goal was to sight my red dot in so I shot 4 shot grouping till I got my NcSTAR red dot centered and each 4 shot group seemed to produce consistent 1 inch groups for me from 30 feet away using a semi rested position. Not bad at all. Stay posted for my official Field Test Shooting video!
Build Quality: TheGamo PM9 Pellet/BB Pistol seems to be made fairly well, fit and finish is very good, the overall weight is good and like the real B&T MP9 has both a metal and polymer construction. The obvious metal parts are the trigger, rear stock swivel, CO2 magazine, internal barrel and I am sure lots of other internal parts. This Gamo pellet shooter is made for Gamo in Japan and is licensed by ASG.
Realism: The Gamo MP9 Blowback CO2 Pellet and BB Tactical Airgun looks pretty much exactly like a real B&T MP9, the size is right and the weight is close. All the parts are where they should be but not all of them work as many are moulded into the plastic shell. The working parts are the charging handle, fold out stock, standard safety, trigger safety and adjustment for the rear sight. There are magazine releases for both the pellet magazine and CO2 magazine but they are not in the traditional locations. It would have been nice if the ejection port cycled when being fired but it is also moulded into the polymer shell.
Very well made and has good weight and feel to it.
Blowback action gives a bit of recoil feel.
Rear sight is adjustable for windage, can also easily add a red dot.
Pre-test shooting results seems to be positive.
CO2 and magazine are both well covered to complete the realism of this replica.
Decent looking replica, fully Licensed B&T MP9.
Trigger feels pretty decent even though it is claimed to be 9.5 pounds of pull.
Lots of rail accessory mounting locations.
Working charging handle.
Fold out stock.
Cons:
Fold out stock is a bit flexible, would have been better in more solid plastic or even metal.
Pellet magazine release is a bit awkward.
No slide catch release or any way to know you are out of pellets other than counting or listening to the sound change.
Looks to have pretty low shots per CO2 like the other Gamo blowback pellet shooters.
Comments:
Overall, I really like the Gamo MP9 Blowback CO2 Pellet and BB Tactical Airgun, unlike the PT-85 and P-25, the Gamo MP9 is an actual replica and a fully licensed one. Not only that, the Gamo MP9 pellet pistol is a very good replica in terms of looks and function. I was able to get decent power and very good accuracy when I performed my pre-test. It's really great to see Gamo come out with a pellet gun replica this time around and what better gun to base it on other than the B&T MP9!
