I agree with Drylok. With a pulled magazine, many guns can still fire with a round in the chamber, so that definitely is not inoperable. It would also be too easy to simply insert the magazine. To make a gun temporarily inoperable and comply with Crookago, you probably would have to either field strip it or install a lock that would prevent the trigger from functioning. In a pistol, you could rack the slide back and then put a cable lock through the action and magazine well, which should effectively make it temporarily inoperable. I love these gun laws because no criminal will ever bother to render their gun temporarily inoperable.
