AB 1471 or AB 1471 Crime Gun Identification Act of 2007 is legislation passed by the California State Senate on September 6, 2007, and then by the California State Assembly on September 10, 2007, with votes of 21–17 and 43–29 respectively.[1]
It was then signed into law by Governor Arnold Schwarzenegger on October 13, 2007, becoming the first legislation of its kind to enact microstamping of firearms. Its implementation was then placed on hold.[2] The hold was lifted in 2013.
California's "unsafe firearm" laws, which include AB 1471, do not apply to any firearms used or purchased by any law enforcement agency.[3]
