California cities ban high-capacity gun magazines

SUNNYVALE, Calif. (AP) — Enforcement issues surround two Northern California cities' bans on high-capacity magazines.

The Oakland Tribune ( ) reported Saturday that since Sunnyvale, Calif.'s ban went into effect midnight Thursday, not one of the now-illegal magazines has been turned in. San Francisco police report that they have no system to track whether any magazines have been turned in for destruction under the new ordinance. San Francisco residents must surrender their high-capacity magazines to police by April 7.

The two California cities enacted laws similar to several other municipalities banning magazines that hold more 10 bullets in reaction to the 2012 mass-shooting at Sandy Hook Elementary School in Newton, Conn.

The National Rifle Association has filed legal challenges to the bans in Sunnyvale, San Francisco and elsewhere. Judges have so far upheld the bans.
