SACRAMENTO, Calif. (AP) - California's approval of even tougher gun restrictions leaves opponents trying to contain the damage within the most populous state and across the country, an effort buoyed by Donald Trump's election.

Proposition 63 bans possession of large-capacity ammunition magazines, requires permits to buy ammunition and forces owners to give up their weapons as soon as they can no longer legally possess them. It increases penalties for stealing a gun and for not reporting the loss or theft of a firearm.

Analysts say the initiative's passage on Tuesday makes it more likely that similar measures will be considered in other states.

Opponents will keep fighting restrictions with lawsuits and a public relations campaign. They are counting on Trump to appoint a justice who will tilt the U.S. Supreme Court against gun restrictions.
