I have been interested in them. The video reviews are very polarizing. Seems like either people love them or hate them. But I am not putting any money down on such a radical design unless I get the chance to shoot one. So until one of the ranges in Central Indiana get one on the shelf for renting and shooting I will pass.
Well I'm no range, but I should have one in central IN here very shortly. I'd be amiable with letting others shoot it at a range/meetup. The counter to that is my schedule is charitably described as "crap" so finding time can be hard.
