I received a question last week about how various prop houses store their weapons. First, there’s how they should be stored. Every prop house I’ve worked at, and every one I know of, keeps their weapons locked up. The depth and breadth of rules and regulations dealing with weapons, theatrical or replica, varies incredibly amongst states, cities, municipalities, and institutions. Locking up is the least you can do.
But I digress. The question was geared more toward the logistics of weapon storage. Props storage is a never-ending compromise between the ease of locating a specific object with the need to cram as many objects into a limited space.
