SACRAMENTO, Calif., July 2 (Our California Times) — California’s new law barring licensed gun dealers from selling certain semiautomatic pistols that can be readily converted into machine guns took effect July 1, and the Trump administration filed suit in federal court to block it.
Assembly Bill 1127 was authored by Assemblymembers Jesse Gabriel of Encino and Catherine Stefani of San Francisco and signed by Gov. Gavin Newsom on Oct. 10, 2025, according to the state legislative record. The law targets handguns that can be converted with a small device often called a Glock switch.
State records say the statute expands California’s definition of “machinegun” to include a machinegun-convertible pistol equipped with a pistol converter. The covered firearms are semiautomatic pistols with a cruciform trigger bar that can be readily converted by hand or with common household tools.
Under the law, licensed dealers may not sell, offer for sale, exchange, give, transfer or deliver the covered pistols. It also bars the manufacture, sale, possession or transportation of a pistol equipped with a converter.
The Assembly’s summary says the measure does not prohibit possession by current owners and includes exemptions for gun dealers, law enforcement and military agencies. State records list the measure as Chapter 572, Statutes of 2025.
