I need some info in replacing the barrel of a 3rd gen SAA that I have. I bought a shorter barrrel, and need to take the factory barrel off. I removed the screw from the ejector rod housing, but it is not budging. I know they are not soldered on, and not pinned on. Anybody done one of these before?? I have done hundreds of S&W's, from J to N frames but never a SAA. Any advice would be appreciated. Please don't advise to send it to a smith around here, because there is no one qualified locally.
