Kadet II Slide Stop(s) ... poorly documented ... my odyssey

[sberres]

  I did a little more looking at the pre B that I typically run the Kadet on. If I use the Kadet pin that works fine with the Omega it looks like it should work just fine. It locks the slide on an empty mag and seems to cycle alright by hand.
  Firing is a different story, however. The slide locks back on empty but also at other random times through all mags. Switching back to the pin that came with this one works 100%. I have no idea where that one came from as it is not an original pre-b pin, but it works.

Great Information to hear.  My Kadet II came with two slide stops and I guess that I grabbed the right slide stop for my 75B, no problems at all.  Fast forward two years and the addition of a PCR and I obtained a new slide stop for free from CZ-USA.  It caught me as strange that there were no stampings to differentiate them apart.  You just solved the mystery of the second slide stop that originally came with the Kadet II.

Thank you for posting.

Thanks for posting this, couldn’t figure out why the heck there were two slide stops.
 
Is your slide stop also hard to remove compared to the 9mm stop?

I just installed a new Kadet II on a CZ75B.  I have several versions of CZ's, and was expecting some issues.  I ordered pn 01610 after a discussion with CZ.  I was told this one worked best in the CZ75B, while pn 01612 is best on the SP-01.  It was disappointing that CZ doesn't offer a threaded barrel for the CZ75B, but does for the SP-01.  There were duplicate slide stops in the box.  Look to be identical to me, so I just used one of them.  The Kadet fit the frame without any modification.  Loading the magazines, even after modifying my Uplula, is a bugger.  I couldn't load the 10th round without the loader.  Off to the range.  It failed to load the first round.  Needed a forward assist.  Fired, and the slide locked back.  Hmmm.  Used the slide release, and fired again.  The slide locked back on every round.  Fed the rounds fine, very accurate.  Just, kind of a single shot.  I was lucky enough to come across an auction with two CZ75B's that have consecutive serial numbers.  AY179 and AY180.  So, I switched the Kadet to the other CZ.  Fit fine, no adjustment.  Still doesn't like to feed the first round.  (I think it's because the mags are so darn tight).  Still acts like a single shot, locking back the slide after each round.  Now, the original CZ75B slide stop is quite a bit different than what's provided with the Kadet.  But, it fits fine with the Kadet.  And, wouldn't you know, it functions perfectly with the Kadet on either frame.  I was also able to  get full 10 round mags to feed without issues.  So, I really like the Kadet.  Very impressed with the accuracy.  CZ, as noted, should improve the installation manual, with info on the slide stops.

  I’ve seen a few pics on the forum where someone has attempted to document the differences in some of the various slide stops. It almost seems that CZ doesn’t really attempt to catalog most of these and there sure seem to be more and more iterations.
  It almost seems like you pick from a bucket of random stops till you find the one that works with your particular frame.  Once you get the right one, though, it’s a heckuva 22!
  Saw a video of a Beretta 76 from Classic a week or so ago. Pretty much the same operation as the Kadet!  It was a dedicated 22 only and a specialized frame for the barrel mounting method, but same operation and similar overall appearance.
