SACRAMENTO, Calif. — Weeks after New York enacted the nation’s toughest gun laws, California lawmakers said Thursday they want their state to do even more in response to recent mass shootings, particularly the Connecticut school massacre.

Democrats who control the state Legislature revealed 10 proposals that they said would make California the most restrictive state for possessing firearms.

They were joined at a Capitol news conference by San Francisco Mayor Ed Lee and Los Angeles Mayor Antonio Villaraigosa, along with several police chiefs.

“California has always been a leader on the issue of gun safety,” Villaraigosa said. “New York has stepped up and stepped forward. California needs to answer the call.”

Among the measures is one that would outlaw the future sale of semi-automatic rifles with detachable magazines. The restriction would prevent quick reloading by requiring bullets to be loaded one at a time.

Lawmakers also want to make some prohibitions apply to current gun owners, not just to people who buy weapons in the future.

Like New York, California also would require background checks for buying ammunition and would add to the list of prohibited weapons.
