Claims5
A specialized underwater pistol for use by divers in eradication of Lionfish in salt water, the firearm comprising:
- a pistol frame, a single action firing mechanism, a barrel having a generally cylindrical barrel wall, 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 with bore expansions forming equatorial troughs leading from the muzzle;
- the firing mechanism including a hammer cam and a trigger cam;
- and,
- 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 plane of the pistol is formed by the barrel troughs when the pistol is fired and shot pieces are expelled from the barrel;
- wherein a minimum barrel wall thickness is designed to withstand pressures developed within the barrel when the pistol is fired and water within the barrel is expelled from the barrel.
