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.

A fire control group has a receiver having opposed sidewalls defining a space configured to receive a fire control group, the opposed sidewalls each defining a pivot pin aperture, the pivot pin apertures being registered with each other, a fire control group including a trigger received in the space, the fire control group defining a transverse pivot pin passage configured to be registered with the pivot pin apertures of the receiver, the fire control group including a pivoting operational element, the fire control group including a pivot pin supporting the pivoting operational element and received in the transverse pivot pin passage and the pivot pin apertures, the firearm having a hand grip aft of the trigger and defining a screw aperture, and a grip screw engaging the hand grip and engaging the fire control group. The grip screw may occupy a medial plane of the firearm.

Provided is a trigger mechanism having a trigger member is pivotally supported by a housing and having a forwardly extending finger portion and an actuation blade portion and a sear fixed in position relative to each other. A hammer pivotally supported inside the housing has a tooth and a disconnector has hook portion. A safety selector movable between safe and fire positions has a first surface that confronts the finger portion to block pivotal movement of the trigger member when in the safe position and a recess that receives the finger portion and allows movement of the trigger member when in the fire position. When the trigger member is pulled, cycling of the firearm action pivots the hammer to engage the tooth with the hook portion and hold the hammer until the trigger member is released to allow the sear to engage the hammer as the hook releases the tooth.

Gun comprising a gun frame, a barrel supported by the gun frame, a slide, translatable longitudinally in relation to the barrel, and at least a hammer, rotatably mounted with respect to the gun frame so as to move at least a firing pin of said gun towards the barrel. A centreline plane crosses said gun between opposite gun flanks, and the rotation axis of said hammer lies in the centreline plane or is substantially parallel to said plane.

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 plurality of retention facilities each operable to selectively restrain the hammer in the cocked position, and when the selector is in the first position to enable discharge of the firearm in response to movement of the trigger to the rearward position, and when the selector is in the second position to enable discharge of the firearm in response to movement of the trigger to the forward position after movement to the rearward position.
