The means comprises a linkage train including an intermediate link carried by the magazine and movable by a first link reciprocably associated with the nosepiece to move a second link associated with the trigger assembly to render the trigger operational for firing the tool. There are locking means associated with the feeder of the fasteners for locking the intermediate link in an inoperative position when the magazine is empty of fasteners.
