This was a repair I read about online to permanantly fix light primer strikes in many Italian single action revolver clones. My Uberti 1875 was no exception and I was getting tired of replacing the consumable cross pins that hold the firing pin in place. They'd only last a few hundred rounds.
I was 90% through when the tap snapped. That last little bit is always the hardest. Shouldn't be stuck too bad. Can anyone offer their services for removal? Pics below....
