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.
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.
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.
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.
