I've never fired one, or seen/ heard one fired in person. I was thinking about buying one a couple of years ago and ended up with something else (for many of the reasons stated here) One thing that stood out to me while doing the usual internet youtube oggling, was the number of people that commented about how loud it was....even outdoors. It's a cool pistol though. If I had the extra cash lying around, I'd buy one (and a 1000 rounds of ammo) just for grins.
