Appl. No.:

09/886112

US Classification:

Abstract:

A manual safety system for reducing the chances of inadvertent discharge of a linear striker fired semi-automatic or automatic pistol equipped with the system. An otherwise conventional pistol is modified by structural changes in the trigger mechanism housing and by the addition of a trigger bar guide, a manually movable safety lever, a pressure plate and a spring. The trigger bar guide and safety lever are mounted to the trigger mechanism housing for linear and pivotal movement, respectively. A portion of the conventional trigger bar, which must be moved in order to effect firing movement of the trigger, is engaged with and blocked by the trigger bar guide which in turn is engaged and blocked by a portion of the safety lever. In order to unblock and enable the firing system, the safety lever is moved by applying pressure to a tab serving as a thumb rest. Rotation of the safety lever disengages it from the trigger bar guide, permitting rearward movement of the guide and the trigger bar and firing movement of the trigger.

Abstract:

A recoil buffer for a semi-automatic pistol having conventional, relatively moveable slide and frame with opposing abutment surfaces limiting rearward movement of the slide in response to firing the pistol. The recoil buffer is a layer of firmly resilient material mounted in covering, contacting relation to the frame abutment surface. The layer of material is disclosed in the form of a washer mounted upon a portion of the slide return spring guide rod. In one embodiment, the washer has a through cut to permit its radial insertion over a stem portion extending between flange and head portions, and the recoil buffer may include a second, resilient washer axially inserted on the guide rod to be positioned against the forward surface of the flange, for contact by the slide abutment surface in the rearward position of the slide. In a further embodiment, the washer is axially inserted on a stem extending rearwardly from the guide rod flange.
