Gamo G-Hammer .177 Caliber Pellets - 400 Pack$13.99
Availability: In Stock
The Gamo GP-20 .177 caliber pellet gun is a straightforward, no-nonsense CO2 air pistol built for shooters who want reliable performance without complexity. Powered by standard 12-gram CO2 cartridges, this non-blowback design delivers consistent 400 fps velocity with alloy pellets—plenty of punch for target practice, plinking, and introducing new shooters to air pistol fundamentals. At under a pound, it's light enough for extended shooting sessions and nimble enough to handle from bench or standing positions.
The 20-round magazine keeps you in the action longer between reloads, and the single/double action trigger lets you shoot in either mode depending on your preference and situation. Fixed sights with a fiber optic rear sight give you a clear sight picture in varying light, so you can focus on marksmanship rather than fumbling with adjustments. The 6.5-inch barrel strikes a practical balance—short enough to be handy, long enough to support controlled, accurate shot placement.
This is the kind of air pistol that works equally well whether you're zeroing in your fundamentals, setting up informal target competitions with friends, or just enjoying some quiet backyard shooting. The non-blowback action means less mechanical wear and fewer moving parts to maintain, making it genuinely low-stress to own and operate. If you're after a CO2 air pistol that does exactly what it claims without needless gadgetry, the GP-20 delivers.
