My dad inherited a High Standard Model B from his brother when he passed away a few years ago. He was finally able to take possession of it this week. He went out and shot it* and it wouldn't cycle. It shoots fine, but he says that the slide doesn't move at all when fired and had to be cycled manually. He's using standard velocity CCI 22 LR rounds. I told him not to use any high-velocity rounds in it because I've seen quite a few warnings that they can cause the frame to crack. I haven't had a chance to look at it yet and my dad isn't really mechanically inclined so I'm going to take a day next week and check it out. I've heard that these are very good guns and I know that my uncle could shoot it extremely well. Anyone out there with experience with these that can give me some pointers? Thanks * He actually had my youngest brother test-fire it first "for safety purposes". I wonder if that's why he had so many sons, to go into danger so he didn't have to.
