A federal judge in Sacramento issued a preliminary injunction on July 3, 2025, blocking enforcement of Californias new microstamping requirement for all new semiautomatic handguns sold in the state. The law, which was set to take effect July 1, mandated that all new handguns be equipped with technology to imprint unique identifying marks on spent casings. Gun rights groups, led by the California Rifle & Pistol Association (CRPA), challenged the law, arguing that the technology is unproven, cost-prohibitive, and effectively bans the sale of new handguns in California. Judge Susan Illston agreed that the law likely violates the Second Amendment by restricting access to commonly used firearms. The state argued that microstamping would aid law enforcement in solving gun crimes, but the court found insufficient evidence that the technology is reliable or widely available. The injunction is a significant win for gun rights advocates and is expected to set a precedent for similar laws in other states. California Attorney General Rob Bonta has vowed to appeal, stating that the law is a critical tool for public safety. Meanwhile, firearm manufacturers and retailers have welcomed the decision, noting that compliance would have required costly retooling and could have led to product shortages. The case underscores the ongoing legal battles over gun regulations in the post-Bruen era, with courts increasingly scrutinizing state-level restrictions. The final outcome may ultimately be decided by the U.S. Supreme Court.
