Types of Licenses:
Premises Licenses - A restricted form of licenses, which means that the licenses will apply only in that specific residence or business. So that means, no bringing out your new glock to shoot some cans at your friends backyards. (Sucks, I know!) This licenses permits the transportation of the weapon and ammunition in separate locked containers to and from authorized ranges and hunting locations.
Carry Business Licenses - A unrestricted form of license. This license allows a concealed handgun on the person the license has been given to, which means no lending your pistol to your buds at the bar unless written approval from the commanding officer of the NYC licenses division. The licenses is only valid to the business name, address and specific handgun listed on the license. So that means you can't get one license for your handgun, then go off and buy six more guns.
