My dad no longer shoots and I do so I would like to inherit his collection of guns. There are multiple pistols/rifles/shotguns. He is a PA resident, I am a Maryland resident. Does paperwork need to be done on any of them? From my limited knowledge it seems like yes on the pistols and no on the rifles/shotguns. If paperwork needs to be done does this mean that I am limited to 1 pistol every 30 days?
