I'm guessing it won't be long before it's in the movies "saving the day". I'm sure some hero, or bad guy, will empty their mag and "finish off" their opponent. Following shortly thereafter will be flocks of mall ninjas and zombie killers purchasing this must have item for their BOB or daily "duties".
Alternatively, it would make a neat collectors piece. And if ya reach a little I guess one could seriously justify it as a useful apperatus for certain "occasions".
Seriously though, it was only a matter of time. It really shouldn't surprise anyone that this has hit the market.
I'm personally waiting for the first real world sighting of it in use by a Police or Military member. The times, they are a changin' - and getting more predictable, too!
