Hammer pivot pin S&W K-22 1947
1I'd post a few pics, but I'm a bit picture challenged at the moment. From a book I have it shows two basic types of hammer pivot pins for Smith & Wesson revolvers. One type is screwed in and the other pushed in. The revolver in question has a pin with serrated edge which in the book indicates a screwed in type. It looks like it may not be fully seated. I'm wondering if I should try to tighten it? I replaced the previous hammer which I suspect was not original but a later mode with a more period correct one. The previous hammer had shown signs of rubbing at opposite sides top and bottom. The pin may be slightly off somehow. Perhaps bent or not seated straight. The bottom quadrant to the right seems high as indicated by the wear on the serrated edge. Thoughts?
