Answer

An original firing pin should work. It is hard to tell how much altering was done to your bolt but the firing pin-bolt face-extractor should all work without modifications that would require a new bolt. Get a new pin and make it work. That is what gunsmithing is all about; fitting new parts and correcting other people’s screw ups.

Thanks Ken. As far as fixing other people’s screw ups, I couldn’t agree more. I’m certain my experience pales in comparison to yours, but of the close to 500 guns that I have worked on, at least half involved fixing something that somebody else had already “fixed.”
