“This letter is almost pointless. If two private citizens in the same state decide to buy/sell a firearm between themselves, why would they even bother to go anywhere near an FFL?”
I’m far from an expert in this, but one reason that I could see is to get a background check on the buyer - since it is not legal to sell a gun to a felon.
...of course, with the Internet, one can do that themselves just as easy.
I think the result of this de-facto registration is to move more gun sales underground...which actually is good, in the end.
As to sales out of state, I think people will just risk it, and claim ignorance if later told the guy was from out of state...but I’m only guessing here.
Looks like there’s such a law regarding handguns in PA.
