kY Jon,
I appreciate your comments and those of others who have posted here. I don’t have the tools or feel I have the necessary mechanical skills to work on the innards of a more “valuable” gun like this Bernadelli.
I bought it used at a local gun shop. The first time I shot it, I had FTF’s with the left barrel. I took it back, and the dealer had his gunsmith work on it (no charge) before I hit it last June. It worked fine, but I might have been using different shells.
The firing pins do protrude all the way when pushed in manually, but the left one is not as smooth as the right. I put a piece of masking tape on the end of a shell with a deep primer hit, and pulled the left trigger. The tape did not break and the mark on the tape appears smaller than the diameter of the firing pin, which might not mean anything. I did note that the left hammer does not retract to the “safe” position off the firing pin. It remains touching the end of the pin.
