The gun is 1-3/4" wide x 1-1/2" high at the butt, tapering to 1-1/2" wide x 1-3/8" high at the muzzle. Luv 2 Dive wanted it as streamlined as possible so I tapered it and rounded the corners so as not to require any ballast for floatation. It sinks by the nose with the 9/32" shaft and floats level with enough buoyancy without the shaft to add a camera mount or reel (hopefully!!) and still have positive buoyancy without the shaft.
I made the handle frame out of 3/16" ( Tin Mans design), but made it about 1/4" longer and a smidge wider to give me a little more room to weld around the front of the trigger guard. Tin Man's welding skills make my stuff look like a blind monkey did it- except for the wood part!

This is the first gun I sanded using the mop sander I made awhile back- awesome smoothness with the 320 grit.
