I am a gun owner and I am thinking about to sell one of my handgun through EE. But I am not familiar with the procedure. I know how to post a sell in EE but after someone commit to buy it what should I do? For instance, what government dept should I call? Do I need an ATT to bring the handgun to the postal offices? Is it me or the buyer to register the gun? If I am the one to help the buyer to register the gun how should I do it? Any info I need to obtain from the buyer in order to register it? Please give me all the steps (web site or phone number) in order to complete the transaction. Thanks everyone.
