Fits great - on my pistol it required no modification so it was a drop in. Others may need to fit/file one part of the safety for proper fit.
Now my right thumb does not need to stretch out to disengage the safety.
Note this is for CZ 75 with the newer D style safety - check the end pin on the right hand side. If it is D shaped this is the one for you.
For installation I referred to this video https://www.youtube.com/watch?v=DPc2TFqpyxgLoading...
