I was thinking of just snapping it with a quick spot of filler and re-cutting the face and hole. Not enough heat to worry the lugs.
When I bush 45 slides, they are threaded in. For a bolt gun I think the bushing would have to be larger than the primer size and have a countersunk feature to keep the stress on the threads to a minimum. I've yet to do a bolt, so its just a theory on my part, but I think thats what I would do. Irritates me to have to do this to a factory screw up in the first place.
