Hey everyone, I'm new to the forum and have a couple questions. I picked up a 442 then needed a 686.... then couldn't resist picking up this 629-2.... the 629 is missing the rear sight assembly (was scoped) I'm not having any luck finding one online. S&w says they don't sell it anymore. Midway is backordered so is brownells and numrich. Any ideas? S&w did give me a part number. 22331
Also anything I need to know about the 629-2? Its 6" barrel, unfluted cylinder, and full underlug.
