I just bought one today! This is my first CZ pistol (Have a couple Sig P226s and a Kimber 1911). I really wasn't intending on buying anything today. I was just getting the front sight post on my P226 replaced (I have had 2 sets of Trijicon HD XRs break on me during install and am sick of not being able to shoot the Sig so I went with a Meprolight FT Bullseye, which seems really nice and I can't wait to shoot).
I was originally thinking of putting a DPP on the Kimber, but that would force me into Open division and I'd like to be able to shoot Classic, Production and Production optics.
Before I bought my first Sig, I handled the CZ SP-01 and decided on the P226 MK25 (my first 9mm). I wasn't a huge fan of the contoured barrel. It found that it made it hard to rack the slide imo. That said, the Shadow 2 OR is really nice. The thing that sold me on it are that it seems to fit my hand really well. It's very easy to pick it up and draw exactly the same way and have it come up perfectly level and lined up, with trigger in perfect position for my finger. Mag release is perfect for me as I require no change of grip to drop the mag.
I obviously haven't shot it yet but I expect to do very well with it. Can't wait for transfer to complete and get a DPP mounted to it. Only real flaw on pistol is the the lack of back serrations, but you're getting this one instead of the standard CZ S2 because you're putting an optic on it, so it's moot imo.
I'll also note that the fiber optic front sight is really nice and so it's more than serviceable without an optic if you have to live without one for a while. I found my sight acquisition really fast with it. Will update once I get to shoot it, both with and without optic.
