Claim:
1. A flotation device mounted on a shot gun, the flotation device comprising a housing; the housing comprising: a first tubular section having an internal surface, an external surface, a proximal end, a distal end, and internal threads defined on the internal surface of the first tubular section adjacent to the shot gun, the first tubular section having a first external diameter; a tubular transition section having a proximal end unitary with the distal end of the first tubular section of the housing, a distal end, and an external surface, the external surface of the tubular transition section having an external diameter which is smaller than the external diameter of the first tubular section; a second tubular section having a proximal end, a distal end, an external surface, and an external diameter which is equal to the external diameter of the first tubular section, the proximal end of the second tubular section of the housing being unitary with the distal end of the tubular transition section; a ring mounted around the tubular transition section for connecting a strap of the shot gun to the flotation device and retained in position around the tubular transition section by the first tubular section and the second tubular section; a closure cap frictionally mounted on the second tubular section adjacent to the distal end of the second tubular section to close the second tubular section in a watertight manner when the closure cap is in place on the second tubular section; and an inflatable arrangement located in the second tubular section; the inflatable arrangement being set to activate when it senses water pressure and to inflate to bring the shot gun to a water surface when the flotation device encounters water; and the first tubular section, the tubular transition section, and the second tubular section of the housing being comprised of a one-piece unitary structure.
