This is completely theoretical and relates to the application of the simultaneous application of a number of laws from a number of states + the country itself. If one had no FID card in MA but had an NH carry license, with all its reciprocal states, would one be allowed to purchase, possess, and operate firearms in those states? Would one be able to store one's firearms outside of the People's Republic of Massachusetts in order to spite a state that makes up its own rules as it goes and is capable of denying anyone for conjured reasons?
