The next generation of ballistic identification technology, known as microstamping, passed an historic testing session in California. The test was conducted at the California Highway Patrol range by California State Assemblyman Paul Koretz, a West Hollywood Democrat. The results were verified by a representative of the California Criminalistics Institute. Microstamping technology utilizes lasers to make precise, microscopic engravings on the breech face and firing pin of a gun. As the gun is fired, information including the make and model of the gun is stamped onto the cartridge.
