I guess there is a lot of stuff out there for the CZ but what would really be cool is if they had a .22 adapter - or better yet, an exact replica of the CZ75 chambered in .22
You can get a KADET KIT for the CZ, which is a complete slide and mags for .22 LR. It'll work on any of the 9mm or .40 models that are based on the 75B frame/specs.
You can also buy a KADET, which is basically a 9mm frame with a Kadet Kit slide installed, as a unit, from the factory. (CZ won't let you buy a 9mm slide later, so you can't upgrade the Kadet with a higher caliber slide, later, unless you get lucky and stumble on a used slide. I've only seen that once, and jumped on it.)
The Kadet and a 75B with the Kadet Kit are virtually the same gun.
I have a Kadet Kit which I use on my 85 Combat. They sometimes take a little fitting. My Kadet Kit, for example, won't fit on my 75B SA frame, which has had a lot of gunsmithing done to it -- including work to give it a tight slide/frame fit. (That was all done before I bought it...)
I could make the kit fit the 75B SA frame, but it shoots so darned well on the 85 Combat frame, I don't want to mess with it.
Instructions for fitting come with the kit.
