Who this affects: The newly signed legislation will introduce phased requirements for California residents and individuals relocating to the state. Starting in 2028, new residents bringing firearms into California will need to acquire a safety certificate within 180 days of relocation. By 2029, current residents purchasing new firearms will be subject to the four-hour safety training mandate. Additionally, individuals convicted of removing serial numbers from firearms will face a decade-long prohibition on ownership.

On September 26, 2026, California Governor Gavin Newsom signed 10 new firearm-related bills into law. The legislative package introduces new requirements for training, data tracking, and manufacturing technology, according to NBC Palm Springs. The new laws also expand behavioral health services for young people exposed to violence.

As reported by CalMatters, Senate Bill 948 will mandate a minimum four-hour safety class for residents buying new firearms. The same bill requires individuals moving into California with firearms to secure a safety certificate no later than 180 days after arriving. The California Rifle and Pistol Association opposed this measure, arguing that mandatory classes act as a financial burden on firearm ownership.

NBC Palm Springs noted that Assembly Bill 2047 mandates that consumer 3D printers available for purchase in the state incorporate software to prevent the creation of firearms or unlawful components. Additionally, Assembly Bill 1974 permits local police departments to create voluntary firearm storage programs.

CalMatters detailed two other significant bills in the package. Senate Bill 1220 imposes a 10-year ban on firearm ownership for individuals convicted of removing a weapon's serial number. Assembly Bill 1743 allows universities and municipalities to request crime gun trace data from the California Department of Justice. Gun control groups like the Brady Campaign supported the data access for research purposes, while the California Rifle and Pistol Association expressed concerns about the privacy of lawful owners.

Emma Brown of the Giffords organization praised the legislation. "The policies enacted today will save lives by closing loopholes," she said in a statement provided to CalMatters.
