A guy I work with has a 629-1 with a 8 and whatever inch barrel,and a safariland leather shoulder holster. Asking $400. I couldnot believe this gun was that old. The gun has no play in it, and the finish has no scratches. The cylinder bores hardly have any carbon build-up. Only thing that looks bad are the stocks and they are not real bad. Holster also looks new. Should I buy?
