I bought this S&W MP circa 1923 at a gunshow and I confess I missed that the barrel was loose. It has FIVE factory repair dates and is marked to J.P.D. 1933. Its been reblued at least a few times. The action is very nice and the bore is also very nice. But I'm lost on what to do about the loose barrel. I thought maybe peening the barrel threads and using locktight, but that was only a thought. I'm open to suggestions.
