  • Patent number: 5560134
    Abstract: A trigger related safety device for a firearm or the like comprising a secondary trigger (24) which is reciprocally movable relative to the main trigger (10) between a first or operative position and a second or inoperative position, and a locking member (35) associated with the secondary trigger (24) which, when the latter is in the said operative position, serves positively to lock the main trigger (10) to a stationery part of the firearm or the like so preventing the main trigger (10) from moving in the direction where the firing mechanism of the firearm will be activated, and when the secondary trigger (24) is in the said inoperative position, the main trigger (10) is free to move in the said direction.

  • Patent number: 5513460
    Abstract: A safety and dismantling device (10) for a trigger operated firearm (18) is provided which includes a lever (12). The lever is slidably movable relative to the firearm (18) from a `safe` position where it serves releasably to lock the trigger (20) against movement in that direction where it can activate the firing mechanism of the firearm (18), to at least a `fire` position, where it does not so lock the trigger. The lever (12) is located toward the front end of the firearm (18) and substantially in the same plane as the firearm (18). Movement of the lever (12) is through a slot (13) in the leading end of the trigger guard (28) of the firearm (18) and the lever can also move to a `dismantling` position where the slide (25) of the firearm (18) can be removed to allow access to the underlying components of the firearm (18) for dismantling purposes.
