While New Jersey does not require firearm owners to register their weapons, all firearms dealers must keep a register of every handgun transferred, and the dealer must record detailed transaction information in the register. This register is then retained by the firearm dealer and the dealer must make the register available for inspection by any law enforcement officer at all reasonable hours. Copies of the register must also be delivered to local law enforcement or the county clerk and the New Jersey State Police within five days of the sale of the firearm.
