Too my knowledge they do not make a Kadet kit for the Tac Sport. I'm sure you can put a SP01 or Shadow II kit on it, but the dust cover will be longer than the slide and the mags will be too small to work in the TS. Unfortunately, CZ no longer makes the Kadet II but still makes the SP01 and Shadow kit. If you can find a SP01 kit it will work on a standard 75b frame. Problem is the plastic mags do not work well with that frame and you would have to get the metal Kadet II mags.
