California Governor Jerry Brown has signed several gun-control measures into law, including one that raises the minimum age for buying rifles and shotguns to 21 from 18.
The new laws, signed Sept. 28, come seven months after a gunman opened fire with a semiautomatic rifle at Marjory Stoneman Douglas High School in Parkland, Florida, killing 14 students and three adults, the second-deadliest mass shooting at a public school in U.S. history.
