I have a lot of play in the Thumbpiece - rotational play relative to the frame,so I disassembled and I believe the surface on the bolt that "rides" against the hammer is excessively worn and allowing the unwanted movement. So I would like to purchase a non MIM replacement. I could probably use a spare bolt plunger spring just in case.
