ABSTRACT:
A locking system for a pistol firing pin integrated within the firing mechanism of a semiautomatic pistol is composed fundamentally of a single part, called a tilting lock (1). The tilting lock (1) is duly housed in a slot (9) located in the lower part of bolt (10) and rotates about a shaft (8) fixed to the bolt itself (10). The lock (1) engages a notch (12) in firing pin (11) by the action of a spring (17) inserted in the slot (9) of bolt (10) and is disabled only at the instant of firing by the action of the projection (16) formed in the shoulder (15) of the arm (14) of the pistol's trigger (13).
