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

This bill creates a $300,000 grant program to help New Jersey retail firearm dealers provide temporary off-site storage for customers' firearms. Licensed dealers can apply for grants up to $5,000 to purchase storage units (like safes or vaults) for customers who want to securely store firearms, particularly for suicide prevention. The program allows dealers to offer this service without charging customers or requiring additional permits. The Attorney General must annually report on grant usage, effectiveness, and unspent funds.
