ABSTRACT:
An automatic pistol with blowback action, in which a hammer is cocked by the recoil of a slidable breechblock, has a retaining member in the form of an elongate lid detachably secured to the gunstock for holding the breechblock in place, this lid carrying a backstop for a restoring spring tending to thrust the breechblock forwardly. The rear limiting position of the breechblock is defined by a pair of upstanding wings, rigid with the gunstock, against which two lateral shoulders of the breechblock come to rest upon manual arming or after the firing of a cartridge. A swingable control element on the breechblock, entrainable by a setting knob through a lost-motion coupling, has a blocking position in which it prevents the hammer from striking a firing pin lodged in the breechblock; in a working position, this element is movably interposed between the hammer and the firing pin to act as a force-transmitting device upon the release of the hammer by depression of the trigger.
