I have to finish reading those manuals RJM sent me, are 1955 pre-25 45 ACP and a pre-27 357 mag N frames pre lock revolvers? they both have five screws if that helps.
I think they started putting the locks on in the 1990s.
Ten Fo, Thanks, we've got that whupped by a long shot, that said, and I realize this is a Colt thread, those old S&W's of mine are indeed tight and smooth, not saying much on my part, but they both shot every load I've put in them better than I have the talent to realize.
