Let it be know that he original Kadet kit for the 75s are a lot different from the newer 22LR slides for the Omega models and the Shadow 2. The original Kadet kit for the 75s has a fixed barrel and a steel slide. The newer options for the other models has a tilting barrel and an aluminum slide. While i am not clear on this, they may be different animals.
Except for the Omega(s), that ONLY work on the KADET 2s

The Slides on the CZ75 KADET (ONE) and CZ75 KADET 2 are of a two piece, steel design:
First there's Main Slide Body, with the Sights and Barrel fixed to it and becomes "pinned" to the Lower when mounted
And the moving Slide or "Bolt" that cycles much like the Browning Buckmark, Colt Woodsman, Ruger Mark Series and the S&W 41
Also, their Magazines have a two piece steel Tube Body with a Plastic Base
The other, newer style KADETs, all have a one piece, Alloy Slide and separate Barrel
These Conversions cycle and function just like any standard Semi-Auto Upper
They consist of the P-07, the P-09, Shadow 2 and the SP-01 KADETs
All of these Kits are Model specific, and use a Model specific, Polymer Magazine
