CA SB452

Removes the microstamping requirement from the definition of unsafe handguns, replacing it with a new regulatory framework requiring Department of Justice investigation by March 1, 2025, to determine if microstamping technology is viable.

Prohibits licensed firearms dealers from selling semiautomatic pistols without microstamping components starting January 1, 2028, if the Department of Justice determines microstamping components or microstamping-enabled firearms are available.

Requires the Department of Justice to establish performance standards for microstamping components by September 1, 2025, accept licensure applications from entities to produce these components by January 1, 2026, and provide grants or contracts to ensure availability by July 1, 2026.

Criminalizes modifying a microstamping-enabled pistol or component with intent to prevent microstamp production, punishable as a misdemeanor (up to 6 months jail and $1,000 fine for first offense, up to 1 year jail and $2,000 for subsequent offenses).

Imposes civil penalties of $10,000 per firearm for knowingly providing false certifications that a firearm is microstamping-enabled and authorizes injunctive relief.
