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

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.

I don't see where Rmach said the problem was solved.

I said to be continued.  I'm expecting the factory new extractor spring to be delivered today.  Barring no problems, I hope to get to the range tomorrow.

Maybe have the extractor spring hole reamed out to fit a CZ or Tanfoglio extractor spring.

I was thinking the same thing, but I will give the factory replacement spring a chance to fix the problem. The C100 ran great the first few thousand, so fingers crossed for another few thousand.

You are right I jumped the gun totally on this.....he said it should do the trick not it did do the trick.
Thank goodness there are people keeping me in line. I am always an optimist - my bad.

The new factory extractor spring was delivered about an hour ago.  I put the caliper on the new one and old one.  The cone shaped springs are identical at the top (.130w) and at the bottom (.150W), and the overall height (.350) with the new spring is ~.010 taller than the old spring. Installation went fine, so back to the range tomorrow with fingers crossed.

I'm back from the range.  The first 59rds ran perfect with very good extraction using three magazines.  At round 60, the first failure to extract occurred (same type of failure as before).  One of the magazines had 3 failures to extract, and the other two had one each. I fired 100rds, and I load 10rds in each mag for reference.

Another disappointing day, and I'm not sure how to proceed.  The spare Wolff extra power CZ spring I have is about .012 wider than the stock extractor spring and is not cone shaped. Should I ream/grind out the angled extractor spring hole in the slide to accommodate the CZ extra power Wolff spring, or should I move on and sell this C100 with disclosures?  I would do the reaming with a Dremel. It's been a fine, tight fitted handgun, and I always said I would never sell it. I ran today with the new recoil spring and extractor spring, both recent factory replacements. The extractor claw looks fine.

I'm all ears right now, and I hope the members with much more experience than I can come up with a good suggestion. This is a $350 handgun that's just over 5 years old with about 4000 rounds fired.

One last note, I did put an unfired round under the extractor claw when I changed out the extractor spring to see how well it was gripping the round.  I shook the slide pretty vigorously and it held the round without a problem.

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

This^^^^^^^ using perhaps a BB, Pellet, or Plastic Rod  just big enough to drop into the Extractor Spring Shaft, to provide a bit of extra tension.

Since you went through some rounds before you started having problems again, you probably don't need much.
Make sure that your Magazines have been cleaned thoroughly, particularly at the Feed Lip area, but the whole mag tube needs it too!

Thanks, the mags are spotless internally.

I made a spacer out of a tiny Phillips screw.  I have two options to install it. Should I place it in the extractor hole with the button end down (shortest adjustment), or should I place it the hole with the threaded end down (tallest adjustment)?  The tallest adjustment would add .130 to the extractor spring height, and the other way would be .050.

I have several of these screws that can be cut to whatever length I want. 

[Gunnerdad80]

I’d try button end down first. You may even need to file down the screw head a little.

[jwc007]

Yup!  Button Head down.

[Rmach]

Ok, thanks to both of you.  I will install it with the button end down that will add only .050 to the overall length.

[Gunnerdad80]

The screw head was a good idea by the way.

Thanks, I just finished installing it, and it took more effort to compress the spring and get the pin in. I use a roll pin punch to align the holes, and then insert the pin that will push out the punch.  I hope it's not too much tension now. I placed a spent shell under the claw, and it's tight, but I cycled the slide and it kicked it out a couple inches.
