CZ doesn't make a nickel stainless model.
They make stainless 75Bs (full size); the also make a number of nickle plated steel and alloy models.
The only compact models available in nickel are the 75 Compact, 75 Compact D, and the PCR (the 75 Compact D and the PCR are very similar.) The 75 Compact is steel, the Compact D and PCR are alloy.
I don't know of any compact models in stainless, yet.
