Witness/CZ Compatibility

[fitzdawg]

I traded into an older steel small framed Witness, and I was wondering if anyone has any insight into what CZ75 components may be compatible? I'm primarily concerned with whether the various springs are swappable with after-market CZ offerings. I looked up the serial number on EAA's website, and it says the sku number is 999111. It looks almost exactly like a CZ75 B, and doesn't have an accessory rail on the dust cover at all. I'm relatively familiar with CZs, but this is my first experience with a Tanfo. I tried searching for this info, but didn't come up with any info.

Grips and mags are about as far as it goes, the internals are all slightly different, what parts are you looking for?

Recoil and hammer springs, trigger return spring, and possibly sights too.

CZs have a much longer hammer spring, and a different sight setup.

Aftermarket recoil springs, yes, but the flat CZ springs won't fit over the Witness guide rod.

 

Some old Witness pistols use the same long hammer springs (they have a plug in the bottom of the frame behind the magwell), but most use the short hammer springs of modern Witnesses.

 

Trigger return springs, yes.

 

Sights have different size dovetails, so none fit without modifications.
