Kids can normally "go with" the parents to take the class (in states where classes are required) and kids can go with the parents when they apply for the permit, but kids cannot get a gun permit.

felony's, age
no you cant,it is illegal. That depends on where you are and what the circumstances are. For instance, in the U.S. almost anyone that isn't a felon can go to a shooting range and shoot. That said though, you can't just shoot a gun anywhere you want to, even if you have a permit. A permit only allows you to have the gun on your person (and actually, in a few states, you aren't required to have a permit). But you can only fire the gun under certain circumstances.

It depends. Some, but only a few, states in the U.S. require a license to purchase a gun. A gun permit normally refers to a permit allowing you to carry the gun on your person in public. Some people use the terms interchangeably, but each state calls the gun permit something different. In Tennessee, it is called a "Handgun Carry Permit." In Florida, it is a "Weapons Permit."
