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.
The FID costs a total of $59. $54 dollars for finger printing. and the $5 FID fee. The permit to purchase is $2, and is valid for 90 days.
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.
