Why they haven't moved to every pistol being nitrated like the P-07/09's I have no idea.
Nitration is a type of surface hardening, as is carburization -- something CZ also now uses on barrels (giving them that ugly black look that scratches so easily, and is often polished off by end users.) The Nitration process is NOT the colored surface you see on the slides, which is applied on top (over) the nitrated metal.
I don't know what CZ is using on the P-07 and P-09 (I have a P-07), but I do know that a nitrated slide is no more resistant to wear or cosmetic scratches -- because there's always a FINISH on top of the nitrated metal, and THAT finish is what shows the wear. If the finish wears away, the nitrated finish is more corrosion-resistant and harder and will hold up better over time. The stuff on top (i.e., the finish) is what resists everyday wear.
Is CZ doing something different with the P-07/P-09 finish? Perhaps. (I have a P-07, but haven't paid that much attention to the finish. I'll look at it later today... Mine is used but new to me.)
I think the CZ satin nickel finish is the most trouble-free finish they offer. (Most importantly, it's not applied over a copper base as was once the case with most nickel finishes -- so it's not something affected by copper solvents.)
I've got a CZ-85 Combat that is almost 20 years old and shot a lot, carried some, but many presentations from the holster (IDPA), and it still looks like new. CZ doesn't offer THAT finish on all models. I've had it on a the 85 Combat and a 75 Compact, and they also did a small run of 97Bs. A matte stainless "finish" (I know stainless isn't a finish) would be almost as good, and easier to maintain than a high-gloss stainless finish.
