Slide stop compatibility for CZ 75 clones

[Rcher]

As I read before slide stop and recoil spring are weak parts of CZ 75 design and should be replaced eventually.
So, I'm wondering about these parts compatibility between various CZ models and clones.

In particular I'd like to know if CZ 75B or Witness small frame slide stop compatible with Sarsilmaz? I searched online and found after-market slide stops available only for CZ and EAA Witness models.

Witness small frame polymer and Sarsilmaz B6P/K2P are interchangeable. I had my SAR pistols and Rock Island MAPP MS (Witness) all disassembled and managed to mix up the slide stops.
 
Wound up trying all three parts in all three pistols, finally realized the Rock Island stop had a different finish than the other two.
