Abstract
A firearm includes a frame and a slide. A firing mechanism for the firearm includes a striker-type firing pin, a trigger, and a trigger bar. A sear inside the frame is pivotally balanced about a central fulcrum, and is biased in a first pivotal direction by a spring. In this position, a rear portion of the sear engages the firing pin. Actuation of the trigger causes the trigger bar to move rearwards for engagement of a forward portion of the sear. This pivots the sear in a second pivotal direction, against the spring, which releases the firing pin. The spring then causes the sear to pivot back for reengaging the firing pin when it returns to its rear position. Movement of the slide to a retired position causes the trigger bar to disengage from the sear (preventing discharge of the firearm) until the slide returns to a battery position.
