I see. Looks like something someone would use to put their guns in so they wouldn't have to worry so much about thieves breaking into their car or stealing their guns out of motel room, etc? So some kid decides to swipe a tennis racket and winds up with a gun instead. Actually, when my vehicle gets broken into the jerks usually take everything that isn't nailed down and make a run for it. Making a semi-bulky gun bag (like say a hockey bag) with a detachable handles and carrying strap would make the most sense to me. Put the carrying stuff inside the bag when stored unattended. If a thief can't just grab it in one hand in a hurry and run, he's a lot less likely to try swiping it.
