I have a head scratcher with my Canik C-100.

[Rmach]

I just called Wolff to verify I was sent the correct spring, and I do have the correct extractor spring for a CZ75b.  The Wolff spring has 7 coils and is .162 dia. The Canik spring is .152 with 7/6 coils.  Also, the Canik spring is tapered .010 form top to bottom.  Wolff does not make an extra power spring to replace that OEM spring.  The closest spring they have in that OEM diameter will not be any stronger than what's in it now. Oh well, now we know Canik/Tristar C100 extractor spring is not compatible with a CZ spring.

I'm going to clean it up and put it back together with the original spring.

Sorry to read if your further troubles. 

A hack I would try, would be to concoct some sort of spacer, at the bottom of the Slide Extractor Shaft.

Now that's a thought, thanks.  That's if I have anymore failures. 

Here's another picture of the extractor and OEM spring. You can see the cone shape the spring has.

One last question, is the standard CZ OEM extractor spring narrower in diameter than the Wolff spring?  If not, then that spring will not work either in the C100.

Nope!

Thanks, I just ordered an AR15 disconnect spring from Brownells. It supposed to be the same diameter, length and conical shape as the stock Canik extractor spring but with slightly thicker coils.  It was $6 delivered, so not much lost if it doesn't fit or work properly. Thanks for the help guys.

I hope it works for you man!!!

Go on witcha bad self MacGyver. Hope it works.

I just received the AR15 disconnect spring, and it looks like it will fit if I remove the wider bottom last coil.  However, the AR spring feels more than 25% weaker than the Wolff extra power spring, so this was a failed experiment, oh well.  I still think the Speer ammo batch I got just doesn't want to run correctly in this C100.  I changed my concealed carry renewal class to early December, so the C100 will not be fired again until then.

I took the C100 back to the range today and fired 100rds of Blazer Brass 115gr.  I had 4 failures to extract, same failure I had with the Speer Lawman. When I got home. I called Tristar, and he agreed the extractor spring is most likely the culprit. As most of you have posted that earlier, I agree with that now.  Anyway, Tristar is sending me a new extractor spring, even though I'm out of warranty.  To be continued.

I've almost NEVER seen the CZ 75 design have an issue (like this)  that was NOT the extractor spring.  I started reading your post on page one and wondered why no one was raising it.  I hope this fixes it.  I DID take a Wolf spring and ground off a coil to get it to fit.

Thanks for replying.  The wolf spring is too large in diameter to fit in my 2013 C100.  I wish it was a matter of removing a coil, but that's not the case with mine.  The new spring Tristar is sending me should do the trick.

Amazing how simple it turned out to be.
That was an exhausting lesson for me to learn here.
Thanks for doing so many things before finally being able to get it right.
Now we can look to this thread and know specifically what not to do if we see a similar problem.

Great teaching tool.

Been on this forum a little while and heard of lots of problems, but again - the extractor, dirt, and spring are likely 98% of CZ 75 problems.  On a .40 you get issues with a 9mm slide stop too.  CZs run.  The 75 design is pretty bullet proof (other than the TRS and slide stop and I think the slide stop is overblown).

I had a similar journey with the Tristar P120 sometimes dribbling out spent cases.  After expirimenting with lighter recoil springs from a tuning kit purchased from CGW hoping an accelerated retraction of the slide would help, I finally poked into the extractor area and noticed a slight kink in the extractor spring.  My first CZ75 extractor coil cut was too crude made from a dike.  Taking the advice from one of the great moderators here, used thinner wire cutters for a second standard CZ75 extractor coil cut and the P120 runs again so far.  Still, would be nice to just buy a couple of spare extractors off the shelf DESIGNED for the application rather than having to deal with the warranty department or modifying CZ OEM parts to fit/function.  I suppose that is what you get with copy cats that don't maintain original dimensions for small parts.  Likely no significant market for the likes of Wolf Springs or CGW to create a purpose built part for the clones.
