Abstract
A semi-automatic pisor of living a slide mounted to a frame is disclosed. The pistol has a hammer assembly and a trigger bar assembly. A trigger bar moves the sear during firing, causing the sear to disengage the hammer. A safety is provided having a cam projection which, upon movement of the safety, provides a caming action to urge the trigger bar downwardly, out of engagement with the sear. A second projection moves to obstruct movement of the sear to prevent firing. Disengagement of the trigger bar from the sear in the safe position eliminates mechanical stress on a forward projecting arm of the sear.
