SACRAMENTO, Calif., July 2 (Our California Times) — California’s new ban on the sale of certain semiautomatic pistols that can be readily converted into machine guns took effect July 1, even as the Trump administration filed suit in federal court to stop it.
Assembly Bill 1127 bars licensed firearms dealers in California from selling, offering for sale, exchanging, giving, transferring or delivering the covered pistols. The law applies to semiautomatic handguns with a cruciform trigger bar that can be converted by hand or with common household tools using a pistol converter.
The statute also expands California’s definition of “machinegun” to include a machinegun-convertible pistol equipped with a pistol converter. Current owners are not barred from possession, and the law includes exemptions for gun dealers, law enforcement and military agencies in future sales.
Gov. Gavin Newsom signed AB 1127 on Oct. 10, 2025, according to the California Assembly. Assemblymembers Jesse Gabriel of Encino and Catherine Stefani of San Francisco authored the bill, which state legislative records list as Chapter 572, Statutes of 2025.
