The CZ 85 is a very nice pistol. It has the same 4.7" barrel as the SP-01 although the frame has no rails (not a big concern for most shooters). The ambidextrous controls are a nice touch -they even made the slide-stop lever ambidextrous! The 85 has a manual safety unlike my SP-01 Tactical with ambi decock. I prefer decock though, admittedly, most prefer the manual safety for some archaic reason... :P
If you can get the model 85 cheaper it would be a great investment in a fine firearm. I know the shadow has target sights and the competition hammer which some prefer but the sights are liable to snag on clothing if the pistol is carried concealed for personal defense. As a target pistol the Shadow is probably more appropraite right out of the box though either gun could be set-up per your preferences after purchase (for additional cost).
They're both great guns. Good luck in your decision and procurement processes.
