A firearm is disclosed which advantageously allows for firing from two different magazines, one in a magazine well ahead of a trigger, and a second magazine held in a handle of a pistol grip of the firearm. This allows for both sub-machine gun and pistol firing configurations, allowing for increased firing capacity and allowing the firearm to continuously fire while reloading.

Trigger groups for striker-fired firearms have 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 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 selector movable between a first selector position and a second selector position, and a connector operably engaged to the trigger assembly and to the selector.

A trigger mechanism or fire control for trigger operable devices includes a housing; a sear having a sear body coupled to the housing and including a primary engagement surface and an active sear support reset geometry; and a sear support coupled to the housing and having a body with a sear engagement surface and a passive sear support reset geometry. The primary engagement surface of the sear is moved into an overlapping condition with the sear engagement surface of the sear support as the sear is moved from a discharged position to a reset position after actuation of the trigger operable device. In addition, interaction between the active sear support reset geometry and the passive sear support reset geometry causes a mechanical displacement of the sear support to a reset position.
