I can tinker on a revolver; some, polishing, tuning etc, but wouldn't make a pimple on a gun smiths azz. I am a shooter though, and concentrated the last 15 years of competitive shooting using revolvers. From a shooters prospective, the Colt is a non starter, S&W is really the only one in the game. In 15 years of highly competitive revolver shooting, a couple International Revolver Championships and many state and local matches, I have never once, seen a Colt revolver on the line. Oops, I take that back, at the 1984 Steel Challenge I saw the one and only Colt, a Python, shot by the then somewhat renowned gun rag writer Dave Arnold. He was the first one to pop a cap at the 84 Challenge, when he drew, he was shakin like a dog [bleep] a peach pit, the revolver spun a time or two in mid air and landed in the parched alkali California dust.
I wish I had a half dozen tucked in the safe so I could make some scratch on them, but for what they were made for, shooting, they just don't cut it.
