And that’s fine, was just wondering. Thank you for the detailed answer. It’s obviously up to the seller, as stupid as it isAll a driver license tells a seller is that you're a GA resident and that you're old enough to take posession of the firearm.
For some sellers, they're not happy unless they can see a GWCL so they have some basic evidence that they can use as a defense if they sell to someone who might turn out to be a felon. I understand the impulse, even if I don't agree with it.
Some sellers want a bill of sale, as evidence that the firearm has definitely left their posession. Again - personally - not my thing, but it is for some people.
Lastly - and this often comes from transplants from other states, they want to effect a transfer AT an FFL.
Ultimately, they're as free to turn down a sale to you if you don't like the rules, as you are to walk away if you feel the seller's conditions are unreasonable.
