Welcome to OCDO.
I strongly suggst you go to the California state forum to ask your question, as it is specific to California state laws and the folks there are the source of knowledge for such things. You will also find a wealth of information about UOC (unloaded open carry) which is apparently a "California thing" and anathema to Free America, as are many of the other bits and piece of regulation you folks have to put up with that the rest of most of us (Sorry, Wisconsin and I;llinois especially, as well as Massachusetts, New Jersey and a few other quirks of legal idiocy here and there like the folks in North Carolina are currently dealing with) are not encumbered by.
The above was not hating on California - it is hating on the way states find to impose and infringe on what should in the best of worlds be an unencumbered right.
stay safe.
