Summary

Existing law, subject to 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, magazine disconnect mechanism, and technology that transfers a microscopic array of characters from the firearm to the cartridge case when the firearm is fired, known as a microstamp. This bill would remove from the definition of an unsafe handgun a semiautomatic pistol without a microstamping component, as specified, and would prohibit, commencing on January 1, 2028, a licensed firearms dealer from selling, offering for sale, exchanging, giving, transferring, or delivering a semiautomatic pistol, as defined, unless the pistol has been verified as a microstamping-enabled pistol, if the department has determined that microstamping components or microstamping-enabled semi-automatic firearms are available, as specified. The bill would also prohibit a person from modifying a microstamping-enabled pistol or microstamping component with the intent to prevent the production of a microstamp. By creating new crimes, the bill would impose a state-mandated local program. The bill would require the Department of Justice to provide written guidance concerning qualifying criteria and performance standards for microstamping components, as defined, if the department has determined that microstamping components are technologically viable, as specified, and would require the department to accept applications for licensure of entities in order to produce microstamping components, as specified. 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.
