ABSTRACT:
A double barreled firearm which may be of the over and under configuration. A removable trigger group or unit is releasably secured to the bottom of the receiver. A selector switch or lever is provided forward of the trigger which cooperates with the trigger unit whereby a selection can be made to fire either barrel in response to the first pull of the trigger with the other barrel capable of being fired immediately in response to the second pull of the trigger. The trigger carries a laterally movable transfer block or member which is adjusted by the selector lever. The transfer block or member has pivoted to it the sear actuator block. A hammer pilot spring rod is provided for each hammer and the ends of these pilot rods cooperate with an extension on the sear actuator block. The sear actuator block is moved laterally to one side, or the other, to engage the sear that is selected to be fired in response to the first pull of the trigger. Upon firing of the first barrel, its hammer pilot spring rod is moved to allow the sear actuator to move to a more forward position whereby to engage a secondary shoulder on the other sear so that the other sear is actuated in response to the second pull of the trigger for firing the other barrel. The mechanism is not dependent on movement of an inertia member.
