My local Cabela's had an ASP in the gun library. I had to ask to hold it. Thankfully, the guy wasn't a dick and obliged. Sadly, the asking price ($4500ish, IIRC) was too far out of my price range and the front door was too far to make a break for it. :-P

And, I agree that the Medusa is a bit of an answer in search of a problem. However, having not been able to get 9mm ammo for any of my handguns once during a trip to Walmart at the height of the panic after Sandy Hook made me consider diversifying my calibers.
