Abstract
A firearm having a firing pin block that does not affect trigger pull is disclosed. The firing pin block embodied in the present invention is actuated by a grip safety operably linked to a spring biased locking plunger to prevent accidental discharge of the firearm. An intermediate lever interposed between a grip safety lever and a firing pin locking plunger pivots on the hammer stud to reposition the plunger from the locked to the unlocked position only when the grip safety is properly depressed.

A firearm comprising:
- a frame having a grip portion;
- a barrel mounted on the frame;
- a reciprocating slide mounted to the frame;
- a firing pin mechanism mounted in said slide for travel between firing and retracted positions;
- a cockable hammer mounted on the frame at a hammer stud and adapted to strike the firing pin;
- a trigger mechanism movably mounted to said frame for activating the firing pin;
- a grip safety means pivotally mounted on said grip portion;
- a spring biased locking plunger supported in said slide for reciprocating movement between a locked position preventing axial movement of said firing pin and a release position allowing axial movement of said firing pin;
- and
- an intermediate lever pivotally attached to the frame interposed between said grip safety means and said plunger for positioning said plunger in either a locked or unlocked position.
