Practical Examples

If you live in California and own a high capacity magazine purchased before the ban, you must register it with the state to possess it legally. Failure to register can lead to confiscation and penalties.

If you bought a high capacity magazine in another state and bring it into California, possession is illegal unless the magazine was legally owned and registered before the ban. Transporting unregistered magazines risks criminal charges.
