Difference between Kadet and Kadet 2 conversion kit???? UPDATE....

[Grendel]

Will the Kadet or Kadet 2 work on the CZ 75 D compact?

The answer is in the post above yours.

Thanks Grendel.

My Kadet2 works on my RAMI pistols(both 9mm & 40cal), my 75B, P-01, and PCR with no problems!

So besides the original KADET (one) Upper, and the KADET II that has the typical thinned at the Muzzle, Slide Profile of the CZ75s
CZCustom offer a KADET 2 that sport the thicker Slide Profile of the B-SA
Also known for being "all steel" and will look "correct" on an SP-01 Frame

And it's not that newer Alloy version of the KADET SP01:

As it turns out CZ started making their newest KADET 2s with the B-SA or SP-01 style, "full rail" Slide Frame
From what I understand, they no-longer make the standard 75 style tapered Slide
I'd guess you'd have to call these, the KADET 2, 2.0
