I know this thread is a little old, and I originally read it as "P-01" rather than "SP-01." No matter, the CZ 75 issues are all about the same.
I have a PCR (same basic thing), and I agree that the narrow slide is uncomfortable; there's no way I can overhand it, because there's not much to grab onto. I flip it horizontally and pull the slide back between the thumb and index finger of my support hand. (I do the same thing with my Beretta 92 for similar reasons, but with the Beretta the slide-mounted safeties conveniently serve as "ears.") Anyway, I agree, I don't enjoy racking a CZ 75.
I think the decocker is fine. I think the double-action pull (from the half-cocked position) is comparable to the Beretta. It's been a while since I tried a double-action pull on a SIG P229, but as I recall it was very stiff.
The standard sights on my PCR are too small (tiny, really), but that's something a set of fiber-optic sights will fix.
The rubber grips (and the contours thereof) are just about perfect. And my gun is relatively light, but it's a compact with an aluminum frame.
On balance, I like the PCR, and the DA/SA operating system with decocker works about the way I would expect it to. But the narrow slide is a CZ thing, and I don't think I'll ever get used to it.
