Yea, you will avoid shipping or FFL fees here. But what I didn't hear said was that you won't pay taxes here. And you very often, for the retail price of a gun, get a holster or ammo included. Also, yea, the federales don't know what you own. That may become REAL important in the next few decades!!!
They can be given a handgun from someone, maybe even buy one from ODT but not a gunstore. Just telling you how it was explained to me from the knowledgeable folks at Ga Firing Line in Marietta. I'm not a lawyer, I just ask a lot of questions,
Pretty sure you can't buy a handgun from a store until you are 21. That's what was explained to me, even thought the law allows an 18-21 y.o. to own a handgun.
