Found, what to me is an unusual, interesting gun at brother RM Vivas' page. Anyone ever hear/see an OP, "round butt," before? I've seen lots of the S&W's in square and round but never a Colt. Is this unusual? Guess it won't take standard grips, huh? Were they made long? Makes me wonder what OTHER pieces there are with the OP label that I don't know about. I'm thinking this would make a terrific PD gun for moi. (AND, there's those 2" barrels from Numrich, too! THINK of the possibilities!) Over?
