Just did what you likely already have done: did internet search and didn't turn up anything.
I think that the differences between the K2 and CZ97 configurations (pic rail/dust cover/frame forward towards muzzle) could give some problems with closely molded kydex holsters, but on most holsters you would be fine going with the 97 holsters, particularly leather or hybrid holsters that have more "give". On the kydex holsters that have a retention adjustment, you could loosen up the clam shell just a tad and should be okay.
