The lever system includes a right release lever and a left release lever; the left lever is an integral part of the bolt catch finger. The plunger rod assembly abuts and connects the right and left levers; a torsion spring on the rod creates tension causing rotation of the bolt catch finger in a downward or upward position. In an upward position, the bolt catch finger engages the bolt, retains the bolt in a rearward position, and signals the operator that the magazine is empty. The bolt engaged by the finger is held rearward in a safe, reliable manner to allow an unobstructed view of the firearm chamber until manually released using either the right or left release lever.

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.
