A semi-automatic pistol has a slide which houses a barrel and a firing pin, and a frame which houses a trigger and a mechanism for releasing the firing pin. The mechanism includes a sear engageable with the firing pin and a cam actuator which is operable by the trigger. The cam actuator prevents movement of the sear to release the firing pin and also operates a detent to prevent movement of the firing pin, until the trigger has moved the cam actuator by a predetermined amount. The firing pin can also be locked in position by a safety catch which can act at the same time on a linkage between the trigger and the cam actuator, to disconnect the latter from the trigger. The operating characteristics of the trigger may be determined by selection of an actuator having a required profile. The firing pin is held captive in the slide and cannot be tampered with.
A semi-automatic pistol comprising a frame and a slide mounted on said frame, said frame containing a trigger, a cam actuator movable by movement of said trigger, and a sear coacting with said actuator, said slide including a firing pin engageable by said sear, said cam actuator including a first portion engageable with said sear to prevent movement thereof out of engagement with said firing pin, and a second portion acting on said sear in response to movement of said actuator by said trigger to disengage said sear from said firing pin only after movement of said actuator by said trigger to disengage said first portion from said sear.
A semi-automatic pistol comprising a frame and a slide mounted on said frame and supporting a barrel and a firing pin, first and second sub-assemblies mounted in first and second housings, said housings fitting in respective recesses in said frame, said first sub-assembly including a trigger which coacts with said second sub-assembly by way of a linkage between said housings, said second sub-assembly including a sear engageable with said firing pin, said second sub-assembly further including means engaging said sear for preventing said sear from releasing said firing pin until said trigger has been pulled by a predetermined amount.
