Anyone out there in cyberspace know where or if a firing pin is availabe for an American Arms Brittany 12 ga. SxS? It was made in Spain and, by the stamps on the action, by Zabala Hermanos. After many thousands of round over the last 17 years, the left barrel no longer goes *boom*. I can see that the end of the firing pin broke off. I hope this isn't going to be a case where someone is going to have to fabricate one.
