The lock problem will likely be a worn sear end or notch. Whatever it is, it can be repaired. If the locks need welding or any repair, send them to Al Edge. He's a magician at fixing locks and is very reasonably priced and fast. He did a brilliant job of welding up and re contouring mangled/broken sidelock sear ends for me. He may be "Old Dominion Firearms"?? Can't remember. I'm on the wrong computer tonite.
