California Approves Prop. 63, Expanding Tough Gun Control Measures

SACRAMENTO (CBS13) - California voters have expanded some of the nation's toughest gun control measures.

Voters on Tuesday approved Proposition 63, banning large-capacity ammunition magazines, requiring background checks for ammunition sales and speeding the seizure of firearms from people who are no longer allowed to own them.

The measure passed by a margin of 63 percent to 37 percent.

The initiative's chief proponent, Lt. Gov. Gavin Newsom, believed voters would be motivated by memories of the terrorist slayings in San Bernardino.

He said the ammunition restrictions and California's unique firearms seizure program would serve as models for other states.

Opponents say the restrictions will likely confuse law-abiding gun owners.

The initiative builds on limits signed into law earlier this year.
