California Microstamping Law Halted Amid Constitutional Challenge

A federal judge in Sacramento issued a preliminary injunction on July 11, 2025, blocking Californias newly enacted microstamping requirement for all semiautomatic handguns sold in the state. The law, which was set to take effect July 15, would have required all new pistols to include microstamping technology that imprints unique identifiers on spent casings. Plaintiffs, including the California Rifle & Pistol Association and several firearm manufacturers, argued that the technology is unproven, costly, and effectively bans the sale of new handguns in California. Judge Emily Carter agreed, citing Second Amendment concerns and the lack of commercially viable microstamping solutions. The states Attorney General has vowed to appeal, arguing that the law is a critical tool for solving gun crimes. The ruling is the latest in a series of legal setbacks for Californias strict gun control regime, following recent challenges to magazine capacity limits and the states handgun roster. The case is being closely watched nationwide, as other states consider similar measures.
