Establishes provisions related to the safe storage of firearms

HB 2401 requires firearm owners in Missouri to store firearms securely when not in use, specifically to prevent access by children or ineligible persons. It defines secure storage as keeping firearms unloaded and locked in devices like safes or trigger locks, with personalized firearms requiring their safety features activated. Violations carry a $500 fine for a first offense and a class B misdemeanor for repeat offenses, excluding antique firearms and curios. The bill also mandates firearm dealers to display warning notices about storage penalties and directs the state to include storage laws on suicide prevention resources for dealers, healthcare providers, and the public website.
