Trigger group for striker-fired firearms

Abstract

Trigger groups for striker-fired firearms have a firing pin assembly connected to a slide and operable to reciprocate between a rearward retracted position and a forward extended position, the firing pin assembly including a retention surface, a trigger assembly including a sear surface configured to selectively engage the retention surface to releasably restrain the firing pin assembly, the firing pin assembly being responsive to the trigger assembly to release from the retracted position to the extended position in response to movement of the trigger assembly from the forward trigger position to the rearward trigger position and to release from the retracted position to the extended position in response to movement of the trigger assembly from the rearward trigger position to the forward trigger position, the trigger assembly including a retainer movable between a clear position and a blocking position.

I claim: 
     
         1 . A pistol comprising:
 a frame defining a medial plane;   a slide connected to the frame and operable to reciprocate between a forward battery position and a rearward recoil position;   a barrel connected to the slide and having a forward muzzle end;   a trigger assembly connected to the frame and having a trigger lever movable between a forward trigger position and a rearward trigger position;   a firing pin assembly connected to the slide and operable to reciprocate between a rearward retracted position and a forward extended position;   the firing pin assembly including a forward-facing retention surface;   the trigger assembly including a sear surface configured to selectively engage the retention surface to releasably restrain the firing pin assembly;   a trigger control facility operably connected to the trigger assembly and movable between a first state and a second state;   the trigger control facility having a plurality of trigger assembly guide surfaces operably engaged to the trigger assembly to move the sear surface out of engagement with one firing pin retention surface in response to a movement of the trigger lever from the forward trigger position to the rearward trigger position; and   another trigger assembly guide surface selectably operably engaged to the trigger assembly to move the sear surface out of engagement with the firing pin retention surface in response to a movement of the trigger lever to the forward trigger position.
