MI SB0079

Requires individuals to store firearms in a locked box/container or use a locking device when a minor is present or likely to be present on premises under their control.

Establishes criminal penalties ranging from misdemeanor (up to 93 days imprisonment or $500 fine) to felony (up to 15 years imprisonment or $10,000 fine) depending on severity, with enhanced penalties if a minor obtains the firearm and discharges it causing injury or death.

Mandates federally licensed firearms dealers include a trigger lock or gun case with all firearm sales (with limited exceptions for police, antique firearms, and buyers presenting their own locking device/case with receipt).

Requires dealers to provide firearm safety brochures, written warnings about storage penalties, and lethal means counseling literature with each firearm sale and post conspicuous notices at sales locations.

Restricts civil liability for gun manufacturers and ammunition producers, limiting lawsuits to state attorney general only and prohibiting local government actions except for breach of contract, warranty claims, or defect-based product liability when the political subdivision owns the firearm.
