I have a 12 gauge side by side that was my Great-Grandfathers. It's about 100 years old & is missing the firing pins. I never owned a gun before but am getting ready to apply for Firearms purchasing ID. I'd like to go hunting & am interested in eventually getting a handgun. But now that I was downloading forms my old shotgun came to mind. Another question is; Do you guys know of or recommend a place to get this shotgun possibly repaired in North Jersey?
