California lawmakers seek to force gunmakers to 'microstamp' bullet casings

Advocates seek enforcement of 2007 measure that would link casings to the guns that fired them

Gun control advocates are making a new attempt to force the gun industry to comply with a unique California law that requires bullet casings to be microstamped", a measure that has been toothless since it was approved more than a decade ago.

California's 2007 law requires gun manufacturers to adopt microstamping technology on new types of handguns introduced in the state. The intent was to imprint a unique set of microscopic characters on all cartridge casings when weapons are fired, linking bullet casings to the guns that discharged them.
