They can own them, but as far as I know they aren't allowed to carry them except to and from a shooting range.
That sounds about as restrictive as CA laws...unless you’re REALLY fortunate and live in a county with a decent sheriff.
We had to lock the UNLOADED gun in a case. Stored in the trunk of your car. The ammo went in another case...in a different part of the car.
Totally ridiculous...We had an SUV and were told that even with the stuff stored in the far back of the SUV, separated, if we got stopped by a cop with an attitude...we could be in heap big trouble.
