Abstract
A semi-automatic pistol is provided having a frame, a slide and an arced cam surface extending longitudinally on an inner surface of the slide. The pistol has a barrel mounted between the frame and the slide, and a firing pin mechanism mounted in the slide. A trigger is mounted on the frame. A trigger bar and a sear are also provided. The trigger bar includes a generally planar surface extending between the ends of the trigger bar. The first end is connected to the trigger and the second end has a sear disconnect surface to engage and disengage a sear rotatably disposed in the frame that engages an end of the firing pin. A tab is disposed at an angle to the generally planar surface, where the tab has a top curved surface to slide along the arced cam surface of the slide as the slide moves.
