Prohibits leaving loaded firearm within easy access of minor under age of 18; requires law enforcement officers who observe unsecured firearms to conduct follow-up.

S 1448 (New Jersey) increases the age of "minor" for firearm safety from 16 to 18 years. It prohibits firearm owners from leaving loaded guns within easy access of minors under 18 without secure storage (locked container, secure location, or trigger lock), making non-compliance a disorderly persons offense. The bill also requires police officers who observe unsecured firearms to return later to verify proper storage. This directly affects firearm owners in homes or premises where minors under 18 reside or visit. The law takes effect immediately upon enactment.
