Are CZ parts compatible with Witness parts? If not, which ones aren't?
I'm really thinking about a Witness and have heard good things about them.

Good question! Wish I knew the answer. You might try looking here:

Shooter1 gave you a good answer. A lot of folks at CZforum who know what they are talking about. Good shooting;)

This is a question we deal with a lot on the CZ-Forum, where we have both CZ and "Clone" owners, some (like me) with both types.
Very few parts of the two guns are compatible.
Slide stops will interchange, but an EAA witness slide stop in a CZ generally won't lock back the slide.
The inner workings are subtly different (because of differences in how the decocker works on decocker models, and the firing pin block linkage in the other models), and things like triggers use different size pins. The EAA guns are simpler, with fewer parts.
Barrels are greatly different. (Most EAA 9mm and .40s have the same outside diameter barrel, while CZs have different sizes for each caliber.)
Sights use different dovetails. About the only thing they have SOMEWHAT in common are magazines, and even those can be a problem, as Witness' mag releases seem to be set just a hair lower in the grip, so that a Witness mag will sometimes need tweaking to work in a "B" model CZ, and won't work at all in a pre-B 75. (Enlarging the top of the mag release notch generally gets them working.) The top of the mags are also shaped differently, and EAA mags will rub on the trigger/transfer bar in SOME CZs. Guide rods are made differently, come in different lenghts, and generally aren't interchangeable.
The safety lever on some EAA models can be adapted to work in a CZ, but generally not the other way -- but it will probably take gunsmithing, regardless.
In the case of the .45s, the EAA .45s have a slightly smaller frame than the CZ .45 -- but they do use exactly the same mags, and no modification is required. (The grip is smaller in the EAA gun, so its better for some hands.) The CZ-97B (a .45) uses a screw-in barrel bushing; the EAA has one that's pressed in.
I'm over-simplifying, but NO, they won't interchange. (You may find exceptions for specific applications.)
