On Tuesday, it became illegal to own a firearm magazine capable of holding over 10 rounds of ammunition in the city of Los Angeles. California state law already bans the sale and manufacture of large capacity magazines, but now it will be considered a misdemeanor to actually possess one within the LA city limits.

The vote was unanimous and Mayor Eric Garcetti has promised his signature on the ordinance. Once the law is in place, owners of large capacity magazines will have 60 days to turn over the contraband, or otherwise get rid of the magazines, before they are considered in violation. Those exempted include on-duty police officers, military, and firearms dealers, according to the Washington Examiner. That report also states that "people who more than 15 years ago obtained high-capacity guns to hold 10-round magazines" are also exempt from the law.

Democratic council member Paul Krekorian wrote the ordinance and said he hopes it prevents mass shootings. "Mass shootings have become so endemic that we can all recite a litany of places where they have occurred: Columbine, Isla Vista, Chattanooga — they've become part of lexicon," he said. "We've become desperate to find some solution to the destabilizing effect of the fact that we have to fear these sorts of mass killings."

Krekorian told the LA Times, "People who want to defend their families don’t need a 100-round drum magazine and an automatic weapon to do it. Imagine what a gunman on this sidewalk could do with that kind of firepower with a crowd like this.”

The NRA has threatened to sue and Krekorian dares them:

If the NRA wants to sue us over this, bring it on.
