SACRAMENTO, Calif. (AP) – California voters are considering expanding some of the nation’s toughest gun control measures.

Proposition 63’s chief proponent, Lt. Gov. Gavin Newsom, says voters are motivated by mass shootings like the terrorist slayings in San Bernardino last year. He says the ammunition restrictions and California’s unique firearm seizure program should serve as models for other states.

But opponents, including law enforcement officials, say the restrictions are likely to just confuse law-abiding gun owners.

The proposal builds on increased gun limits signed into law earlier this year that also address ammunition sales and ammunition magazines holding more than 10 bullets.
