3D Animation: How the Unique HK P7 Pistol works

The HK P7 was a blowback-operated semi-automatic pistol designed and manufactured by German gun manufacturer Heckler & Koch (H&K) from 1978 to 2008, chambered in 9mm (9×19mm Parabellum). It featured a unique gas-delayed blowback system, which used gas pressures from the ignited cartridge and fed them through a small port in the barrel (in front of the chamber) to retard the rearward motion of the slide. This was accomplished by a piston contained inside a cylinder under the barrel. The grip featured a built-in cocking lever located at the front of the grip. Squeezing the cocking lever cocked the firing pin. If the lever was released, the weapon was de-cocked. Check out our Gun Apparel at: We ship worldwide.
