SACRAMENTO, Calif., July 2 (Our California Times) — California’s AB 1127 took effect Wednesday, barring licensed firearms dealers from selling or transferring certain semiautomatic pistols that can be readily converted into machine guns, while the Trump administration filed suit in federal court to block the law.
The statute applies to semiautomatic pistols with a cruciform trigger bar that can be readily converted by hand or with common household tools into a machine gun using a pistol converter, according to California’s legislative record. The law also expands the state’s definition of a machine gun to include a machinegun-convertible pistol equipped with a pistol converter.
Assemblymembers Jesse Gabriel of Encino and Catherine Stefani of San Francisco authored the bill, and Gov. Gavin Newsom signed it on Oct. 10, 2025, according to an Assembly news release.
The Assembly said the law does not prohibit possession by people who already own the affected pistols. It also includes exemptions for gun dealers, law enforcement and military agencies in future sales.
The legislative record lists AB 1127 as Chapter 572, Statutes of 2025.
