    (c) a carrier for a pellet mounted at the opening for holding the pellet in the opening so that the pellet can pass through the barrel;

    (d) a pistol grip means supporting the head means;

    (e) a drive rod linearly moveable through an opening between the ends of the head means and into the barrel from the pistol grip;

    (f) an actuating means mounted in the pistol grip for moving the drive rod into and out of the barrel; and

    (g) trigger means mounted on the pistol grip and having opposed sides which slide into the pistol grip and actuatable by the fingers for moving the actuating means and thus drive rod into and out of the barrel, wherein the actuating means is a pivotable linkage means mounted on a pivot means on the pistol grip adjacent the trigger means and between linearly movable holder means for the drive rod and an inside portion of the trigger means, wherein there are arcuate openings on the opposed sides of the trigger means which are movable over the pivot means when the trigger means is moved into the pistol grip, wherein a spring means is mounted between the pistol grip and linkage means to return the linkage means and the trigger means to a rest position after the trigger means is released from being moved into the pistol grip, wherein the linkage means, holder means and drive rod are moved by movement of a surface of the linkage means on a roller bearing mounted on the inside portion of the trigger means and wherein the linearly movable holder means for the rod is mounted in a slot in the pistol grip and the holder means with the rod is moved by the linkage means in the slot and wherein the linkage means passes through and out of an opening in the holder means and pushes the holder means as the trigger means is actuated to move the holder means and rod so that the rod is moved into the barrel of the needle.
