This pistol comes with a pellet clip that holds 16 rounds (each end of the magazine features a rotary clip holding eight pellets each). The P-430 features a textured grip and a tactical rail underneath the barrel that allows mounting accessories like lasers or lights. It also features semi-auto action and fixed sights. CAUTION: Only use standard-skirt pellets with Gamo CO2 pistols. To avoid damaging your magazine, never use long-skirt pellets, such as Red Fire, Blue Flame, Glow Fire, PBA Bullet, Magnum, Master Point, Armor, Lethal, Rocket or TS-10.Features :Caliber: .177Action: Single/DoublePowerplant: CO2 12gr.Slide: Non-blowbackVelocity: 495 feet per second (fps) with alloy pelletsAmmunition: .177 Cal Pellets / BB's.
