+Existing law, subject to exceptions, generally makes it an offense to manufacture or sell an unsafe handgun, as defined, and requires the Department of Justice to compile a roster listing all of the handguns that have been tested and determined not to be unsafe handguns. Existing law establishes criteria for determining if a handgun is an unsafe handgun, including, for firearms manufactured after a certain date and not already listed on the roster, the lack of a chamber load indicator, magazine disconnect mechanism, and technology that transfers a microscopic array of characters from the firearm to the cartridge case when the firearm is fired, known as a microstamp.
