That is expensive but may have a use.
Personally I would prefer to conceal with an old looking backpack, computer case or thick chambray shirt with it slung on my back. Hopefully none of those methods will ever have to be employed.
If you have a large farm, ranch, or woodlands, these would be very handy for quick reaction operations (but if you do, you are probably rich and can afford them). I'll just use my single point sling while out in the woods.
