There are two different sets of laws, Federal and State. Federal law, which applies anywhere in the US, requires that a person be 21 to purchase a handgun from a licensed dealer. However, Federal law does not address POSSESSION of a firearm, other than by persons forbidden to have any gun (convicted felons, etc). GEORGIA law requires that you be 18 to purchase a firearm. An 18 yr old cannot buy a handgun from a dealer, but COULD be given a handgun, or buy one from a private citizen of the same state.
