CZ75B .40S&W Extractor Issue: How common?

[Lobo_79]

Very interesting. I have a new CZ 75B in .40 and I have had several FTE's after breaking it in with over 1000 rounds and several cleanings.

The extractor spring change solved my problem.  I tested the new spring last weekend with the three types of ammo I had on hand firing more than 100 rounds without issue.  After I swapped out the spring it was obvious the original spring was weak.  It was extremely difficult to pivot the extractor with the +25% Wolff spring installed.  The original spring on the other hand could be easily pivoted with finger pressure on the extractor.   

My science project isn't over though.  Fixing the extractor spring pointed the way to a weak recoil spring. In the 100 rounds I fired I had one instance of a FTF that was easily overcome by tapping the slide into battery. So it's back to Wolff for their 16 # recoil spring, and off to the range to make sure I got all the bugs out of this great gun.

I wasn't bothered by having to do this work on a used gun.  After all springs are like fan belts.  They need changing periodically before they fail completely.  I'm not sure how I'd react if I had bought my CZ75B new.

If you'd like to try the Wolff +25% extractor spring PM me with your address and I'll send you one.  I bought 3 so I have at least one extra.

The CZ Custom Shop says it uses Win White Box to test fire after gun work.

I've never had any problems with it either.

My 9mm had a few extraction problems that were cured with the Xtra power extracter spring.

Just looked at some prior posts and tried to do a search under FAQ and Home Gunsmithing to find some step by step on replacing the extractor spring on a 75B and I found nothing in either place.  Any tips to where I can review the step by step procedure?  I find "bits and pieces" of info but nothing that goes from start to finish...I'd appreciate it mucho.

But...I found it easier to drive the extractor pin all the way out using the extractor punch available on the CZ Custom site. I installed a Wolff XP spring and it was much easier to install if you use the punch as a guide to line up the pin on re-assembly. As it was it was a two person job - for me at least - to install the extra power spring.  It was not difficult but it was also obvious why I was having extractor difficulties with the original spring.  It was seriously weak compared to the new one.

This, in turn, led me to another observation. When using the extra power extractor spring it makes sense to also switch to the 16# recoil spring.  The two together resolved all of my extractor problems.

Good luck...it's pretty easy to do this your self.

Thanks, Lobo...looks like something I can give a try...

My 0.02, coming from personal experience and observations:

Had erratic extraction on Shadow - works 100% for a couple of range trips, works not but stovepipeing alot.
Pulled extractor out. I drove extractor pin from top of the slide down, not all the way but till extractor fell out, with spring. Spring was weakish, and worn on outside of coils, made me think it was larger than needed in overal diameter and was binding/getting stuck due to much friction. New +25% spring (from czcustom) was installed, gun failed chambering test - spring was longer than factory and got fully compressed on installation, it could not compress anymore, extractor would not pivit. Pin, extractor and spring are back out, spring is cut to match factory lengh, all installed back. All tests went fine.
I also used nail polishing emery board to polish extractor's top and bottom surfaces, cleaned cavity in slide and claw as much as I could (they were clean, actually). Also, thou gun was bought brand new, I was surprized to see extractor being 'three dot' one.

When I installed my +25% extractor spring it was extremely difficult to pivot the extractor via normal methods, and yes, the new spring is longer.  But, I could chamber a round ok, and on the range, the extractor worked fine.  I had one instance of a FTRB condition and the new recoil spring resolved that problem. Now the extractor will create a pile of empty brass even though it's extremely difficult to pivot it by hand.  The old extractor could be pivoted with your finger nail. Clearly, each experience is different.  In my case it was the combination of the extractor and recoil springs that solved my problem.

I didn't pivot extractor by hand but used wooden chopstick to push with and test it

Copy.  I used the end of a Nylon tooth brush and it still wasn't easy. It seems to have taken the extra force of the new recoil spring to ensure the slide returns to battery.  Although I'm pleased with how the gun is performing I'm thinking there is now a bit of a new break in period. Since this is basically a range gun for me I'm going to continue evaluating the reliability.  The extractor on my Kahr PM9 works very much the same way.

I have had the same experience with the WWB also.  A new extractor spring helped a lot, but a new extractor solved the rest of this isssue.  And I had similar problems in both .40 and 9mm.

Love the price of the WWB but hate the hassles, so when I'm shooting a CZ I shoot something else.
