A trigger assembly for a firearm includes a housing with an opening adapted to receive a trigger bar guide portion of a trigger bar. The opening includes a ridge that extends downward from an upper surface of the opening. The trigger bar guide is forced downward in the opening by a connector as the trigger is pulled to cause a first disconnect of a striker resulting in a first firing. Upon release of the trigger the trigger bar guide moves upward and upon return to a released position is forced downward to cause a secondary disconnect of striker resulting in a second firing.

A trigger assembly includes a trigger housing body, a firing pin retainer, a first trigger sear, a twisting switch housing and a twisting switch. The firing pin retainer is mounted to the trigger housing body near a top thereof so as to pivot about a transverse axis. The first trigger sear is mounted to the trigger housing body so as to pivot about a transverse axis and is configured to selectively support the firing pin retainer to retain a firing pin. The twisting switch housing is at least partially contained by the trigger housing body. The twisting switch has proximal and distal ends and is mounted within the twisting switch housing. The twisting switch is configured to, at a first twist angle, set a first firing mode for the trigger assembly and, at a second twist angle, set a second firing mode for the trigger assembly.

Pistols having a plurality of operating conditions have a frame having a trigger, an elongated slide connected to the frame and having a rear end facing a user, a moving control element on the elongated slide and positioned in a first position when the pistol is in a first operating condition, and positioned in a second condition when the pistol is in a second operating condition, an indicator on the moving control element visible to the rear, indicia on the elongated slide having a first element associated with the first operating condition and a second element associated with the second operating condition, and the indicator being registered with the first element of the indicia when the moving control element is in the first position, and the indicator being registered with the second element of the indicia when the moving control element is in the second position.

Trigger groups for semi-automatic firearms have a frame, a hammer connected to the frame and movable between a cocked position and a striking position, the hammer being biased toward the striking position, a trigger element connected to the frame and movable by a user between a forward position and a rearward position, a selector connected to the frame and movable between at least a first position and a second position, a disconnector having a hammer engagement facility adapted to selectably engage the hammer, a disconnector control element movable between a first control position and a second control position, the disconnector being operably engaged to the disconnector control element, the disconnector operable to move in a first range of motion when the disconnector control element is in the first control position, and in a second range of motion when the disconnector control element is in the second control position.
