New Jersey requires people to have a Firearms Purchasers Identification Card (FID), to buy a firearm. There is also a separate permit required for each handgun purchase. This permit is only good for one purchase, of a handgun. Applicants must be 21 or over to purchase a handgun, 18 for other firearms.
What is Permit to Purchase?
Some states require that a citizen acquires a permit, before they purchase a gun. If it is required, there will be a fee that varies from state to state. Some states also require finger printing, and background checks before issuing the permit.
