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 state records say can be readily converted into machine guns, even as the U.S. Justice Department filed suit in federal court to block the law.
Gov. Gavin Newsom signed the measure on Oct. 10, 2025. Assemblymembers Jesse Gabriel of Encino and Catherine Stefani of San Francisco authored the bill.
Legislative records define the covered firearm as a semiautomatic pistol with a cruciform trigger bar that can be converted by hand or with common household tools using a pistol converter, a device often described as a Glock switch. The law bars dealers from selling, offering for sale, exchanging, giving, transferring or delivering those pistols.
State records also say the measure expands California’s definition of a machine gun to include a machinegun-convertible pistol fitted with a converter, and it prohibits the manufacture, sale, possession or transportation of that combination. Legislative summaries say the law does not bar current owners from keeping their guns and includes exemptions for law enforcement, the military and firearms dealers in future sales.
