I 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 I always enjoy the chance to shoot even the most basic of Airguns. I would say the Gamo GP-20 Combat CO2 BB Pistol in this category is one of the nicer options as I 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!
