Official Summary Text

AB 1127, Gabriel.
Firearms: converter pistols.
Existing law prohibits any person from selling, leasing, or transferring any firearm unless the person is licensed as a firearms dealer, as specified. Existing law prescribes certain requirements and prohibitions for licensed firearms dealers. A violation of any of these requirements or prohibitions is grounds for forfeiture of a firearms dealer’s license. For purposes of these provisions, existing law defines “machinegun” to mean, among other definitions, any weapon that shoots or is designed to shoot automatically more than one shot, without manual reloading, by a single function of the trigger.
This bill would, on and after July 1, 2026, prohibit
a licensed firearms dealer to sell, offer for sale, exchange, give, transfer, or deliver any semiautomatic machinegun-convertible pistol, except as specified. For these purposes, the bill would define “machinegun-convertible pistol” as any semiautomatic pistol with a cruciform trigger bar that can be readily converted by hand or with common household tools into a machinegun by the installation or attachment of a pistol converter, as specified, and “pistol converter” as any device or instrument that, when installed in or attached to the rear of the slide of a semiautomatic pistol, replaces the backplate and interferes with the trigger mechanism and thereby enables the pistol to shoot automatically more than one shot by a single function of the trigger. The bill would make a violation of these provisions punishable by a fine, a 2nd violation punishable by a fine that may result in a suspension or revocation of the dealer’s license and removal from certain centralized lists maintained by the Department of
Justice, and a 3rd violation punishable as a misdemeanor that shall result in the revocation of the dealer’s license and removal from certain centralized lists.
Existing law prohibits the manufacture, sale, possession, or transportation of a machinegun, except as authorized. A violation of these prohibitions is punishable as a felony.
This bill would expand the above definition of “machinegun” to include any machinegun-convertible pistol equipped with a pistol converter and, thus, prohibit the manufacture, sale, possession, or transportation of a machinegun-convertible pistol equipped with a pistol converter.
Existing law, subject to certain exceptions, generally makes it an offense to manufacture or sell an unsafe handgun, as defined, and requires the Department of Justice to compile a roster
listing all of the handguns that have been tested and determined not to be unsafe handguns. Existing law establishes criteria for determining if a handgun is an unsafe handgun, including, for firearms manufactured after a certain date and not already listed on the roster, the lack of a chamber load indicator and a magazine disconnect mechanism.
For any pistol listed on the roster on January 1, 2026, that was not subject to the above-described requirements to be on the list because it was submitted for testing before specified dates, that is thereafter only modified to change the design features that brought the pistol within the definition of a machinegun-convertible pistol, and that is submitted to an independent certified laboratory for testing pursuant to the above-described testing provisions before January 1, 2027, this bill would authorize that pistol to
be submitted for testing and added to the roster without meeting those requirements.
This bill would make these provisions severable.
This bill would incorporate additional changes to Section 3273.50 of the Civil Code proposed by AB 1263 to be operative only if this bill and AB 1263 are enacted and this bill is enacted last.
By creating a new crime and expanding the application of an existing crime, this bill would create a state-mandated local program.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that no reimbursement is required by this act for a specified reason.
