I recently shot one. A friend of mine has one. It's a nasty gun. It's extremely inaccurate past about 20 feet. But if you're wanting it for a close range self defense weapon, in you're car or in your bedroom it'll do the job. The ultimate anti car-jacking weapon is what my buddy calls it. I think he wants someone to try to steal his car just so he can say "I am the _________ Judge!"
This site had a good video about it but they are in the progress of updating so I'm not sure when it will be back:

But If you search "The Judge" you probably could find it
