My first S&W was a really worn 4" square butt Model 10 police trade in that I picked up for 35 years ago for $100. It was still tight but the muzzle had so much holster wear it almost looked flat on the sides. I cut it to 3", round butted it, bobbed the hammer and cold blued it. I had it for several years until a buddy offered me three times what I paid for it....still wish I'd have kept that one too.
Please make sure you keep this one!
