SACRAMENTO — California Governor Gavin Newsom signed six gun safety bills into law, expanding gun violence restraining orders, restricting 3D-printed firearms, and imposing new training requirements for gun buyers. The measures take effect Jan. 1, 2027.

One bill expands who can petition courts to temporarily remove firearms from individuals deemed a danger to themselves or others, moving beyond immediate family members and law enforcement. The expansion could increase temporary firearm confiscations across the state.

A second bill targets "ghost guns"—3D-printed firearms with no serial numbers. The law requires such weapons to meet federal serialization standards, closing a loophole that allowed home manufacturing of untraceable guns.

New provisions mandate enhanced safety training courses and more rigorous background checks for firearm purchasers, particularly first-time buyers. The requirements aim to reduce accidental shootings and ensure responsible gun ownership.

Newsom has consistently backed stricter firearm regulations, citing public safety concerns. Gun rights organizations are expected to mount legal challenges to the laws, potentially leading to prolonged court battles.

State agencies, gun retailers, and gun owners will have until Jan. 1, 2027, to comply with the updated regulations.
