Establishes firearms storage grant program; appropriates $300,000.

This bill establishes a state grant program to help licensed firearms retailers in New Jersey provide temporary off-site storage for customers' locked firearms, primarily to support suicide prevention efforts. Retailers can apply for grants up to $5,000 to purchase storage units (like safes or vaults), and the program prohibits retailers from charging customers for this service. The bill appropriates $300,000 from the General Fund to fund these grants, with funds carried forward until depleted. It also requires the Attorney General to submit annual reports to the Governor and Legislature detailing grant awards, program effectiveness, and unspent funds.
