SACRAMENTO, Calif., July 2 (Our California Times) — California’s AB 1127 took effect July 1, barring licensed firearms dealers from selling certain semiautomatic pistols that can be readily converted into machine guns with a pistol converter, according to the state legislative record.
The measure expands California’s definition of “machinegun” to include a machinegun-convertible pistol equipped with a pistol converter and prohibits the manufacture, sale, possession or transportation of such a pistol equipped with the device, the record shows.
Assemblymembers Jesse Gabriel of Encino and Catherine Stefani of San Francisco authored the bill, and Gov. Gavin Newsom signed it Oct. 10, 2025, according to an Assembly press release. The law does not bar current owners from possessing the firearms and includes exemptions for dealers, law enforcement and military agencies in future sales, according to the press release and bill summaries.
The Los Angeles Times reported that the Justice Department filed suit in federal court on the same day the law took effect, seeking to block it.
USA Today reported that California’s official roster of handguns certified for sale had already excluded more than 30 Glock models and more than 100 firearm models overall since early 2026.
