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.

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-cycled firearms have a frame, a barrel, a bolt assembly connected to the frame in registration with the barrel and operable to reciprocate between a retracted position and a forward battery position, a trigger lever connected to the frame and operable to move between a forward rest position and a rearward actuated position, and the trigger lever operably connected to the bolt to move the bolt from the forward battery position to the retracted position and to release the bolt to the forward battery position and discharge the firearm in response to movement of the trigger lever from the forward rest position to the rearward actuated position when the bolt is in the forward position. There may be a connector bar pivotally connected to the frame and operably engaged to the bolt assembly and to the trigger lever. The connector bar may be slidably connected to the bolt assembly.

A slide for an automatic pistol includes a cavity, a housing in the cavity, a laser module at least partially received in the housing, a power source, circuitry, and a striker. The slide has a first mode in which it emits laser light and a second mode in which it does not emit laser light. The striker has a first position in which it does not cause the laser module to emit laser light. When the pistol's trigger is pulled, the pistol's firing pin contacts the striker and moves the striker backwards from the first position to a biased position. When the firing pin moves out of contact with the striker, the striker moves forward to a second position and causes the circuitry to transmit power from the power source to the laser module, which causes the laser module to emit laser light.

A triggering mechanism for a weapon may include a moveably arranged trigger; an actuator slidably arranged along a path; and a releasable coupling. The releasable coupling member may be configured to couple the actuator with the trigger such that when a pulling motion is exerted on the trigger, the actuator moves in a first direction along the. An adjustable stop member may be configured to stop the movement of the actuator in the first direction at an adjustable stop position, such that further pulling motion on the trigger causes the actuator to be released from the trigger and to be moved in a second direction along the path. The second direction is different than the first direction. A sensor may be configured to detect movement of the actuator in the second direction and in response to the detection transmit a trigger signal.
