A friend is visiting from Florida and he told me he has been told that state law trumps Federal law and you can cash and carry a handgun from a tag sale there. If this is so, then there are such loopholes. Otherwise, in my experience, in states I've lived in, want to buy a handgun, an FFL is involved. This is why I cannot understand why such a big deal is made about the gun show loophole by politicians as this is limited to rifle and shotgun sales between private individuals only.
