Got an old side by side 410 in today that only shoots from the lh barrel, on further inspection the firing pin is missing the whole tip. I can't find anything about it or any possibility of parts, but that dosen't really matter as i would rather fix this one. How do i go about it though? was thinking use hardened drill rod, drill (w/ lathe) .5" into remainder of pin, silver solder, cut flat to breech and set protrusion. I'd love to post pics if anyone can tell me how...
