I am wanting to try to sell/trade my HK USP9 at a gun show next weekend. The thing is, I am only 20 and the gun is in my moms name :X In GA you can buy rifles at 18, but no pistols. I have always heard that you can buy a pistol from a private party at 18, just not from a shpo/store or anything like that. So do you think I could get a bill of sale from my mom saying I bought it from her, and legally sell/trade it for cash or a rifle at the show? Or would this not work? Any ideas would be great..
