a lot of folks seem to think brass frames are about as robust as silly putty, or play doh, and it's just not so. I had a brass framed ''Colt'' Navy cut down to a Sherriff's model that I got in 1974, and converted to .38 S&W [short stubby, not .38 Special] in about 1979, useing a Kirst like conversion with no name I got from the back of a men's magazine. Not knowing any better, I shot smokeless loads in it. For years it was my only cartridge revolver, and it got plenty of use. Later on I sold it, then bought it back, and found it was a little loose. the new owner had ignored my advice, and used .38 Special, and a lot of it, after haveing moved to Alaska.I peened around the arbor, and shot it for about another five years before selling it to an old gent for a ''shadow box'' decoration. so yeah, brassers shoot loose, but not over night.
