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.
