For what it’s worth, you can only purchase handguns in your own state of residence per federal law, so nobody is driving to GA or any other state with looser laws and purchasing a handgun legally unless they already live there. And having a resident of the state with looser laws purchase them would also be illegal.

Yes, residents of those states traffic guns to states like PA as per the linked story, but people straw purchase in PA as well despite having UBCs for handguns.
