The state and Federal Laws that govern the sale of firearms apply at a gun show the same as anywhere else. If you are a licensed firearms dealer (and people that are in the business of buying and selling guns for a living are required to BE licensed) you must follow the same rules and procedures as if you were selling a gun in your shop. A private citizen may sell a gun at a gun show without those procedures, just as if they had put a "for sale" ad in the local paper. Some states have additional restrictions beyond the Federal law. A popular misconception is called "The gun show loophole"- when in fact, there IS no "loophole". If it is illegal for you to buy a gun at the shop, it is illegal to buy one at a show. If you cannot sell a gun to a minor at your home, you cannot do that at a show.
The answer to that depends on where you are located. We get questions from all 50 US States and several other nations. In MOST of the US, there is no license to purchase an ordinary rifle, shotgun or handgun. You must provide the dealer with a government issued photo ID and complete a Form 4473 at the dealer's shop. The dealer will run a computer background check to determine if you are legally eligible to purchase a gun. You must also be at least 18 to purchase a rifle or shotgun, 21 for handguns.
The same laws in existence for purchasing firearms under any other circumstances in your state apply to gun shows, as well.
