I had this exchange with Ready Holster for anyone looking for an inexpensive holster:
All the CZ75 variants go in the same holster since they all basically
have the same size and shape. Since the Kadet attachment doesn't change
the overall size and shape it will still use the same holster as without
the Kadet attachment. So to keep things simple I'll give you the links
for the holster sizes below:
Size BA-15 fits 4.5" to 5" barrel semi-autos with no attachments on the
rail. So this will fit any CZ in the entire CZ 75 series that has the
4.7" barrel length, but will not fit any of them if there is an
attachment on the rail. Here is the listing for it (open carry belt
holster):

fit any CZ in the entire CZ 75 series with the 4.7" barrel and would
work with an attachment on the rail like the SureFire X300. However,
this holster won't work well if there is no attachment on the rail (open
carry belt holster):

attached and sometimes not...you'll need both holsters. If you are
always going to have the light attached, then you would only need the
BA-15L (2nd link above).
We don't carry any holsters that would work for IWB concealment with the
light accessory attached, but we do have one that will work without any
accessories attached here:
