An automobile is a 2,000 pound hunk of steel capable of travelling in excess of 100 miles per hour and you are allowed to drive it in heavily crowded areas. It can be every bit as deadly as a firearm.
Under federal law when dealing with a Federal Firearms Licensee, also known as an FFL, you have to be at least 18 years old to purchase a long gun, and at least 21 years old to purchase a handgun. You also have to pass a criminal background check. You also have to register it with law enforcement. If you want to carry that firearm in public, you need to get a special license for that as well. As far as carrying it in public is concerned, try walking into a shopping mall and un-holstering a firearm. The police will be called immediately and you will be arrested at gunpoint.
