ABSTRACT:
A trigger-engaging plug for a firearm having of the type that is a trigger guard defining lateral openings and a trigger. A rear portion of the trigger is spaced from and in opposed relation with a portion of the firearm frame. The plug includes a base portion having a size and shape corresponding generally to one of the lateral openings. The plug also has a trigger-blocking projection extending from and positioned generally at one end of the base portion. The trigger-blocking projection defines a lock shackle-receiving bore. A tang extends from and is positioned on the base portion and in opposed relation with the first or trigger-blocking projection. The trigger-blocking and tang define a recess of a size and shape corresponding to a trigger. When the plug is inserted in the trigger guard of a firearm, the trigger is received within the recess, the trigger-blocking projection is positioned behind the trigger to prevent the trigger from being actuated, and the bore is positioned to receive a lock shackle between the rear of the trigger and the firearm frame. Another embodiment of the invention is for single action and other firearms with less space between the trigger and frame behind the trigger.
