Re: the two slide stops. One is for the full-sized and compact steel pistols. The other, which is longer, is for the PCR/ P-01.

Have you tried the 9mm slide stop as Den suggested?

My first (CZ) Set-up was the same as yours, a Factory mated 75B-SA and KADET Kit
They came with only one Slide Stop
I knew that the KADET Kit came with its own / separate Slide Stop, but not in this case
So I call CZ to ask and as per the recommendations of the Head Pistol Smith at CZ-USA (in 2003) "Use the same Stop for Both (9mm and 22)"
Hope this helps

I just tried the 9mm slide stop with the Kadet magazines.  Does not work at all: the 9mm stop is shorter than either of the .22 stops
and doesn't engage on the Kadet magazine follower.
That's interesting.

Like I said my 9mm slide stop that came with my 85 Combat works perfectly whether actually firing, or just pulling the slide back on an empty mag.
I had the right to remain silent...

but not the ability.

Yeah, that is interesting
If the B-SA Slide Stop is too short to reach the Follower on the KADET Mags, not sure how it reaches the Follower on the 9mm Mags
So tell me again how Trump was worse then the 8 years before .... AND what's coming after HIM !

I called CZ USA today, and they have agreed to replace the magazines under warranty.  They also confirmed
that Kadet kits are shipped with 2 different slide stops, so I'm shipping them too so that they can verify
that I have the correct one.

The Kadet Kit comes with two dedicated 22 LR slide stops.  To determine which to use, disassemble your pistol, insert a slide stop into the lower, then insert a .22 magazine.  Observe how the magazine follower contacts the slide stop.  The end of the slide stop should ride freely on the notch on the magazine follower, but not force the body of the follower sideways.  If the slide stop is too long it will cause problems feeding and will not lock back on an empty magazine.  One of the two stops provided, should fit correctly, and one will be too long.

Thanks for the info.  I sort of guessed that the shorter one was the one to use.  Talked with CZ's parts guy today: he had no idea.
CZ is sending 5 new magazine springs to me under warranty, so hopefully I'll be back in business soon.

     Hiya, sorry you haven't been able to enjoy your .22 lately,hope thats the last fix you need. Surprised to hear the person they put you in touch with didn't have a clue. I've called and had the first person connect me to a gunsmith to listen to the problem,write the work request,and handle my shipping slips, I'd lean towards asking to talk with a smith when the rep is not as knowledgable as the instance requires for ideal customer support. When I called with your issue they knew the fix was a different slide stop, sent one for free, problem solved. On ammo, the wall mart 550box of .22lr always worked perfectly,once the 17lb,or up to 22lb mainspring was in the mix.Number mags and help identify rule them in/out when stoppages occur.File ejector as previous posts document,match recoil spring to ammo velocity and have fun. Good luck. Be well.

I find it unlikely, while not impossible, that all 5 mag springs are defective.

Keep us posted.

True, but I know that I had more than one magazine give me problems.  I numbered my magazines after
this started, but never was able to figure out the pattern.  The feed problem doesn't happen all the time,
so it takes a lot of shooting to diagnose.  In the end, CZ offered to replace all the springs, so I'm going
with that.  It's not like I have a lot of options here.

I read somewhere that CZ changed the 9mm slide stop to a shorter one at some point in time.  My 75 is probably newer than your Combat, which
would explain it.

There has been two different Slide Stops for the CZ75
Note the difference in the Lug Shapes:

So, I cleaned all the magazines again, and assembled them dry with the new springs.  Slide
locks back on an empty mag every time and after shooting it today, I think I can call this thing
fixed.  No feed issues at all. 

It's great to get my Kadet "back": this thing is just too much fun.

I am having a hard time thinking that 5 magazines went bad, especially with only 1200 rounds thru the gun. Usually a mag can take quite a bit of use. If they were rotated, that is 240 rounds per mag. Not quite fully broken in yet.

Springs absolutely get a set, so it is normal that when new, the last few rounds would be harder, than when you use them a little.

Take the slide off, and put the slide stop in, and then insert a mag. You will see clearly if the mag/slide stop contact is correct. You should also see the slide stop fully raised by the mag. Sometimes the slide stop and magazine don't mate up properly. Then a new slide stop would be needed, but it is better to know this before you send parts back.

On one of my guns, the slide stop spring ( on right side) was especially stiff.  Den's trick didn't work on this one. I made a tool to help me bend it a bit, and now it is fine.

CZ's although great arms, seem to have a lot of variation and tolerance stack.

Good luck

As (I think) I said before, I don't think all 5 went bad, but I know that more than one went bad.  But,
I hadn't figured out exactly which ones.  CZ offered to replace them all, so I went with it.  So far,
everything is working fine, so clearly, at least some of the springs were the problem.  The usage on
my springs was inconsistent since I bought the 3 extras after I had the Kadet for a while.

As far as the slide stop goes, I've already checked it like you suggested and have the correct slide stop
in place.  What threw me off initially was that I assumed that the two slide stops that came with the
Kadet would be the same, which they weren't.

The slide stop spring is fine, and as I said, the gun has been flawless in 9mm all along.  I've owned the
gun longer than I've had the Kadet kit, so if that spring were giving me problems, it would have been
obvious a long time ago.

So, I think I've got it solved, though a bit more range time should confirm that.  There was another post around
here recently where someone else had feed problems with his Kadet, and new springs solved it as well, so I'm
thinking that Kadet springs can be a bit inconsistent.  I already checked with Wolff, and they don't offer springs
for the Kadet.   But if I start to have more problems, I know what to do.  My magazines are numbered now.

Part of the reason this took so long to resolve was that in the beginning, I thought I had an ammo problem, not
a problem with the gun, so I spent a bunch of time testing different types of ammo.  And because it occurred
intermittently, it took a lot of shooting to get to occur enough times to figure out a pattern.  In the end it was
easier to just change the springs rather that blowing through a bunch more ammo to figure it out.

Thanks for the suggestions.

    Hiya canthelpit and thanks a bunch for your thread and then taking the time to revisit and engage the operators comparing alternative solutions to the issue you began the thread for. I think we all wanted to know how the manufacturer was going to approach and solve your issues, and the spring replacement worked. After seeing about 15years of posts related to the Kadet kits ejector issues,it was refreshing to see a relatively new kadet issue. Noticed on todays cz-usa website,for the 400dollar kit the disclaimer *due to differences in frame dimensions,slide may not lock back after last round on cz85,85 combat,PCR and P-01."  That makes your issue magically become a non issue for hundreds of thousands of cz owners,right?  Glad your story had a Mr. Kraft ending. Be well.
