just to clarify....you cannot buy a handgun at a 'show' in one state and bring it back to another state without transfering it THROUGH an FFL dealer.
buying one from a private person is another matter.
edit: apparently this was already clarified.
never mind.....nothing to see here.....these are not the droids you're looking for.....move along...
Absolutely incorrect. In most states, if you buy a gun at a show as a private transaction, there is no record of the sale.
