SB-452: Microstamping: standalone certification regime

Signed into law. See the bill page for its effective date.

SB 452 removed the dual-place microstamping criterion from the Unsafe Handgun Act definition and created a standalone regime. DOJ published performance standards, began accepting microstamping-producer license applications January 1, 2026, and must determine by July 1, 2027 whether microstamping components or enabled firearms are available. Commencing January 1, 2028, and only if availability is determined, dealers may not sell or transfer a semiautomatic pistol unless it is certified microstamping-enabled; private-party transfers and pistols delivered to a dealer before that date are exempt. The bill also recodified the roster three-for-one removal rule.
