Some years back I made a washer out of an appropriate thickness feeler gauge that fit over the crane barrel between the fixed washer on the crane and the front of the cylinder. This set back the cylinder eliminating barrel/cylinder drag and endshake. After many thousands of rounds fired the Python is again in need of adjustment. Does anyone know of a sourse of these 'Python washers'? I know Power Custom makes makes washers (they call them bearings) for S&W's but nothing for Colt. I know the proper way to do this repair is stretching the front of the cylinder but I don't have this task specific tool or a lathe. By the way, my Python has a 'transition' crane, a late style crane but with the early fixed washer on the crane barrel.
