When in doubt about a certain law and your state municipal/penal code doesn't answer your question, I have found that if you write to your State Attorney General you can usually get the right answer, since he or she is the highest ranking law enforcement officer in the state and is often the person who ratifies the laws.
Just be prepared to wait while for your answer and you may have to write more than once. I,m still waiting for the answer to the question of whether or not high capacity pistol magazines are legal in California since the ban expired 3 years ago and I' ve written 4 times now.
