Trigger Pull: The trigger pull on the Gamo GP-20 Combat CO2 BB Pistol is the same as pretty much all of the DOA trigger low cost BB Pistols where the trigger has to do all the work. Much of which is pulling back the fairly strong internal hammer spring which in this case is the barrel which protrudes slightly out of the front of the pistol until you reach the release point, and it snaps back hitting the valve and pressurizing the Airgun. This will give you a bit of a finger workout if you are shooting fast and want to empty out the 20 round magazine.

Accuracy: 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, we 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. We then averaged the shots out and was impressed with a much higher than claimed velocity of 422 fps. Our 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, we 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), we 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 us we were 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.

Build Quality: The build quality of the Gamo GP-20 Combat CO2 BB Pistol is what you expect from almost all plastic BB Guns of this type. It is not super heavy but that means less can break when dropped on a hard surface. Fit and finish are good and one gripe I have with most of these types of BB pistols built the same way, is that the grips are a bit lose so it can pop off when you pull it back. The Gamo GP-20 Combat’s grips are a lot more solid and this does help make the Airgun feel a bit more confidence inspiring.

Realism: The Gamo GP-20 Combat CO2 BB Pistol from what we can see is not an exact copy of a real steel pistol in production but it does look like a modern semi auto pistol in design. The barrel is slightly recessed, and the CO2 tab is also hidden inside the grips, so unless you get close to the pistol you would think it could be the real deal. That said some giveaways are the moulded into the slide ejection port and the screw holes on the right side of the two plastic halves of the Airgun along with the kind of out of place standard safety switch that looks more like something you would find on a piece of electronics.

Pros:

Very low cost and simple design will make it reliable.
Fit and finish looks decent for an all plastic gun, grip are actually pretty tight.
Picatinny rail for adding accessories like a laser or tac light.
Standard metal stick magazine found in lots of Airguns for cross compatibility.
Right hand screws are very small and less obvious then some other two sided low cost plastic Airguns.
White dot sight up front and fiber optic in the back are easy to see on all backgrounds..
Safety is right above the trigger finger so easy to switch if you are right handed.
Recessed barrel for added realism.

Cons:

Some more metal would have been nice, but typical of a low cost BB shooter like this.
Double action trigger does require some work, so action shooting will be a bit harder.
Not a lot of working parts other than the trigger, safety, and magazine release.

Comments: We have reviewed many CO2 BB Pistols built exactly like the Gamo GP-20 Combat CO2 BB Pistol, so it is at least for me, not the most exciting Airgun review but we always enjoy the chance to shoot even the most basic of Airguns. We would say the Gamo GP-20 Combat CO2 BB Pistol in this category is one of the nicer options as we feel Gamo stepped up the build quality just a bit, even if it was just to make the grips feel more solid and less prone to popping off when loading CO2. It is a little bit beefier than similar CO2 BB Pistols in this category so maybe not the best for smaller handed individuals but good for someone like me with larger mitts. The price is right for sure and with its simple design, it should perform as expected for a good long time!

www.replicaairguns.com Type: NBB CO2 BB Pistol. Manufacturer: Distributed by Gamo. Model: P-20. Materials: Plastic & metal. Weight: .97 pounds (439 grams). Total Length: 7.25 inches (184mm) Barrel: 4.25 inches (108mm) metal non-rifled. Propulsion: CO2 x 1. Action: Semi auto NBB, double action only trigger. Ammunition Type: 4.5mm steel BB's. Ammunition Capacity: 20 round metal stick magazine. FPS: Claimed 400. 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.
