SACRAMENTO, Calif., July 2 (Our California Times) — California’s new law barring licensed firearms dealers from selling certain semiautomatic pistols that can be readily converted into machine guns took effect July 1, and the Trump administration sued the state the same day to block it.
Assembly Bill 1127 was signed by Gov. Gavin Newsom on Oct. 10, 2025, according to the California Assembly and the state legislative record. The measure was written by Assemblymembers Jesse Gabriel of Encino and Catherine Stefani of San Francisco.
State records say the law expands California’s definition of “machinegun” to include a machinegun-convertible pistol equipped with a pistol converter. It also bans licensed dealers from selling, offering for sale, exchanging, giving, transferring or delivering those firearms.
The bill covers semiautomatic pistols with a cruciform trigger bar that can be converted by hand or with common household tools into a machine gun using a pistol converter, according to the legislative record.
Assembly materials say the law does not bar current owners from possessing the pistols and includes exemptions for law enforcement and military agencies. The legislature chaptered the measure as Chapter 572, Statutes of 2025.
