A specialized underwater pistol for use by divers in eradication of Lionfish in salt water, the pistol comprising:
- a pistol frame, a single action firing mechanism, a barrel having a generally cylindrical barrel wall encircling a barrel axis, a free end, and a rotatable magazine;
- the pistol for firing five or more shot pieces from a cartridge designed to fit within the magazine;
- the barrel having a substantially smooth bore but for opposed barrel troughs leading from the free end and formed by bore expansions along lines about parallel to the barrel axis;
- the firing mechanism including a hammer cam and a trigger cam;
- and,
- the hammer cam including a spur that lies along and operates along an arc of an arc circle centered on a hammer cam pivot;
- wherein a shot pattern elongated with respect to an axis perpendicular to a longitudinal barrel axis is formed by the barrel troughs when the pistol is fired and shot pieces are expelled from the barrel.
