ABSTRACT:
A fire control mechanism for a firing pin striker operated semiautomatic double action handgun includes a sear pivotably disposed on a frame between forward and rearward positions. The sear includes an edge portion for controlling the firing pin and further includes a cam surface for downward displacement of the sear to release the firing pin in response to trigger firing movement. The firing pin includes an extension adapted to be in planar movement with the controlling edge of the sear with selective engagement and disengagement therewith in response to angular and translatory movement of the sear upon response to actuation of the trigger. A trigger bar includes a disconnect portion disposed to move the trigger bar downwardly upon recoil of the slide. The sear, firing pin extension, cam surface and trigger are all movable in coplanar relationship with one another and the trigger bar and disconnect are movable in a plane parallel thereto.
