Thanks for posting this. Am considering purchasing one myself. Have you acquired yours yet? Looking forward to hearing about your first impressions after you get a chance to run a few rounds through it.http://www.charterfirearms.com/products/Charter_Pitbull_74520.asp
It's on their webpage. It's on Gunbroker. People on the internet say they have one.
I'd say it's close to reality. I want one and am working in it.
