It depends upon the state that you live in. But you must have a cocealed carry permit in most states. It is a good idea to be sure before you do it or it could be a very big felony.
21 years old
The same as it is to own a gun... 18. Just don't be committing a crime, waving it around, or be in a gang.
In PA you have to be 21 to conceal carry (or carry loaded in your car) a handgun.
No, you may not. Federal law requires that you be 21 to own a handgun, or under adequate supervision to possess a handgun (which in this case you're neither). If discovered by law enforcement, this constitutes illegal possession of a handgun, which is taken very seriously.
Yes, in Texas one can carry a hand gun in the motorcycle saddlebags. A person can also carry a handgun in plain sight while traveling.

Virginia does not require a license to purchase a gun, nor to possess one. A Concealed Handgun License IS required to carry a concealed handgun in public places if you are not a law enforcement officer, or one of the few others permitted to carry concealed. If you are 21, can own a handgun legally, can pass a background check, and demonstrate that you have had adequate training in firearms, Virginia will issue a concealed handgun license.
