Abstract:
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, and a plurality of retention facilities each operable to selectively restrain the hammer in the cocked 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 and to enable an additional discharge of the firearm upon release of the trigger to the forward position.

Claim (Index 1):
A trigger assembly for a firearm comprising:\n 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; and 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 to maintain the firearm without discharging upon release of the trigger to the forward 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 rearward position and to enable an additional discharge of the firearm upon release of the trigger to the forward position; and the frame including a cam surface, and at least one of the plurality of retention facilities has a cam follower adapted to follow the cam surface and generate a movement of at least one of the plurality of retention facilities to cease restraint of the hammer by at least one of the plurality of retention facilities.
