Here is what I found on the NJ legislation site from A1302...I see no mention of having to (proactively) send ammo info sales to Murphy, --- only on request:
(key items from below: 1) The records shall be available for inspection at all reasonable times by any law enforcement officer....2) "Every dealer should shall establish a system" ---To me this implies each have a system, doesn't sound like a central database in the heart of Murphy's NJ....3) "within 12 months of the effective date..."
e. Records of sales. Every manufacturer and wholesale dealer shall keep a detailed record of each firearm and all handgun ammunition sold by [him] the manufacturer and dealer. The firearm record shall include the date of sale, the name and address of the purchaser, a description of each firearm and the firearm’s serial number [thereof]. The handgun ammunition record shall be in electronic form and shall contain the date of the transaction; the type, caliber, or gauge of the ammunition; the quantity of ammunition sold; the name and address of the purchaser; and any other information the superintendent shall deem necessary for the proper enforcement of this chapter. The records shall be available for inspection at all reasonable times by any law enforcement officer.
Every manufacturer and wholesale dealer shall establish a system for maintaining electronic records pursuant to this subsection within 12 months of the effective date of P.L. , c. (C. ) (pending before the Legislature as this bill).
