I have a CZ91S and quite enjoy it. I think they go in the $1200 range. I picked mine up at an auction years ago for quite a bit less. As far as I know, the ones brought to Canada were all .380. Mine is unbelievably accurate, which surprised the heck out of me. So sometimes when I'm feeling naughty, I use it at bullseye matches instead of my Walther GSP. You should see some of the guys howl and say "What's that, an Uzi? That's illegal!".
It's fun for what it is, but here's my beef with it: To anyone reasonable, it is a "Handgun". It's a semi-only version of a machine-pistol. Yet the RCMP are calling it a "Commercial Version" (Which isn't even a real definition under the Criminal code or firearms act) and thus supposedly the magazines can only have 5rnd capacity. The flip-side though, is since it's not designated a "handgun", you can theoretically get them in .32 ACP.
Again, in a pot-stirring mood, I tried to enter a "Military rifle shoot" with it, and the organizer howled about how it wasn't allowed and the CFO range approval would be yanked if I used it. So if HE deemed it a pistol, I then went over to the "Military pistol" competition portion and won that. (Two years in a row.)
It's a fine example of how f-ed up the Canadian regulations are. We go through the fiasco of the .22 copies of MP5's and Swiss rifles are prohibited as variants. Yet this one is totally okay.
Anyway, my more than 2 cents worth as an owner.
