My buddy has an m19 that he bought used. The hammer nose broke after 80 rounds. After much digging he found a new nose and rivet. The nose pivots up so high it will hit the frame and give light primer strikes 1/3 of the time plus gouging the frame. We "fixed" it by slipping a piece of a staple between the hammer and nose. Works fine, doesn't look to good and i'm thinking we should not have to have to use a staple to get am m19 to fire! New nose and rivet, any ideas? (it is the correct nose, not the later style that uses a spring)
