I think I broke my Medusa... I bought a box of 9mm at a yard sale, and they were super hot (The primer fused with the head of the case after shooting!! ) It still shoots rimmed cartridges fine, but the firing pin isnt hitting the rimless rounds hard enough... It looks like there a "dent" in my hammer, like the firing pin slammed back into the hammer. Since my 'Dusa is far from a museum piece, Im thinking of spiffin' it up.. Most of the internals (including the hammer) are the same as a S&W K frame, so I think I can get a new one.. Can I get a new case hardened one, or maybe a titanium one? Would a certain material or style be better? (If available??) What is this Duracoating ive been hearing about? Would it resist the wear that happens on the cylinder? Other finishes? Some snake-skin grips like Cane?
