I've held and examined one. I like it. It is very similar to the CZ75 Compact, only lighter with a couple of minor differences (a more streamlined rear sight, serrations on the front of the slide, and a decocker rather than a regular safety). Of course, its main appeal is the aluminum alloy frame that makes it a little lighter than the standard models.
A friend of mine bought one last week for $399.95 at my recommendation (he doesn't know much about guns). We had both ordered some CZ high-cap magazines before they were banned here in California. I'd probably have bought one too, but I'm already waiting for the 30-days to pass so I can complete the purchase of another handgun (and my wife's going to flip if I don't slow down a little!). I'll get one eventually.
The standard CZ75 high-cap magzines are supposed to fit, but will stick out the bottom a little. High-caps for the compacts (which should fit perfectly) cost a little more. I paid about $50 from CDNN (I got two, but exchanged one when it obviously wasn't new or original CZ - be specific and request the curved floorplate). I plan to carry a compact high-cap in the gun, and two standard mags for reloading.
Finally, the gun is only available in the black polymer finish (I checked with CZ). I also wish it had the regular CZ75 safety, and a screw-adjustable rear sight. Also be aware that it still feels a little heavy compared with the new plastic framed guns. It feels good in the hand and should shoot comfortably, but may still be a little heavy to carry around.
