The P7 is a semi-automatic blowback-operated firearm. It features a unique gas-delayed blowback locking system, which used gas pressures from the ignited cartridge and fed them through a small port in the barrel to delay the rearward motion of the slide.
The grip of this pistol features a built-in cocking lever activated by gripping the pistol handle. Before the pistol can be fired, this lever must be squeezed. Thus this lever acts as a safety. If the lever is released, the weapon is immediately de-cocked and rendered safe. This method of operation dispensed the need for a manual safety selector while providing safety for the user carrying the pistol with a chambered round, and increased the speed with which the pistol could be deployed and fired.
