CA Attorney General Rob Bonta released a report finding that firearm microstamping technology is technologically viable when imprinting a unique microscopic array of characters, referred to as a microstamp, on spent cartridge cases discharged by a firearm into which a microstamped firing pin has been installed. This report follows recent amendments to the Unsafe Handgun Act, including requiring that new semiautomatic pistols must have microstamping capabilities that allow law enforcement to trace a shell casing to the pistol that fired it. “My office’s investigation into the technological viability of microstamping components has found that this technology is viable. Microstamping technology could help law enforcement match cartridges found at crime scenes directly to the firearms they came from. Today, my office released a report outlining the findings of our investigation in an effort to provide appropriate transparency as to the basis of our determination.” – AG Bonta
