What kind of ammo were you using, and have you cleaned the pistol completely recently? Check to make sure you don't have anything like grit or gunk impinging on the extractor.
ETA: Most failures are due to reloads or debris. Or, is it a brand new pistol and needs a few hundred more rounds through it? |

I was using walmart winchester val pacs. I also tried some blazer in it after the first 3 problems. I also cleaned it at the range after the first 3. And it had a little over 150 rnd through it before today with no problems.

you have about 300 rounds total thru the gun?
I agree with kpel: look very closely around/under the extracter to make sure there isn't something in there. |

Since you are going to take the extractor out, you should replace the spring with a Wolff spring.
The part number for a three pack is 89893 CZ-75 Extractors 20% extra power. I replaced the factory spring in my .40 ST with the Wollff after having FTEs when it was new. I haven't had any FTEs since I swapped springs, and that was about 12,000 rounds ago. One lot of my practice brass has been loaded 7 times so it's pretty beat up.  EDIT: By the way, Mike at CZ-USA was the one who recommended the Wolff spring for FTEs. |

It's a shame, but I've pretty much come to the conclusion that CZs tend to be undersprung to begin with. It seems one is always best served by replacing the recoil spring and extractor spring almost immediately. Other than that, I've not encountered any other issues with any of my CZs that I can remember.
[Edited 08/21] Undersprung in this case means the spring is weaker that it's rated, not just a spring that's "too light". I believe the P-01 uses a 17 lb spring, but the factory spring may only test out at 14 to 15 lbs. -- Mike |

My CZ does not like Winchester whitebox. It'll shoot CCI Blazer alum case all day. Federal Hydrshok all day and Ranger SXT all day. But not the damned WWB. Go figure.

One of the best USPSA shooters I know, Matt Mink, uses a CZ and when he gets a new one from the factory it's already got new springs in it. He said he won't even fuck with the stock springs.

It seems to be about a 50/50 proposition that a CZ will have issues with the WWB ammo. Some believe that that the extractor groove is just different enough to cause this. I quit buying the WWB 'cause I felt it was inconsistent. Never had a issue with functioning, just didn't like it. Brass reloads well for me, so I do find some use for it. :) -- Mike |

If you examine the rim of WWB carefully you will see how thin it is. This is the reason it doesn't perform reliably in some CZ and XD pistols. My first XD would consistently have a 2% FTE rate with WWB. When I switched to American Eagle it was 100% reliable.

 I just got a CZ P01 in 9mm that I haven't had a opportunity to fire yet. What recoil spring do you recommend? The factory is at 17 LBS and Wolff comes in 18, 20 and 22 LB varieties. Thanks, Dave

Shoot it first. If it's launching the empties into low earth orbit, then pick up the replacement 18 lb spring from Wolff. If it's not, use it as is. I wouldn't use anything heavier than 18 lbs for the 9mm.
If you had the Compact .40, I would recommend nothing stronger than 20 lbs springs for it ... if it needed replacing in the first place. Just remember any time you replace the recoil spring with a stronger one, you will get more velocity in closing the action which can be damaging too. -- Mike |

I would not worry about the recoils spring but I would recomend a 17lb hammer spring. I hate the factory one. |

I remember having this conversation a while back, but can't remember with who... Anyway, I may not have made myself totally clear. For the most part, I totally utilize the stock CZ springs. There are a few instances where I don't, but most of my Production pistols have the stock springs in them. Some others I have changed out the recoil spring with a Wolff, or use a Wolff mainspring, but that is only for special applications. For general use, the stock CZ springs are ok. If you wear one out, I would just buy a Wolff replacement and be done with it. As far as the original question, there is no point to go higher in weight on a P-01 recoil spring. I thought the stock one was on the heavy side, but it always worked with whatever I fed mine. |

Replace the extractor spring with a Wolff extra power spring and your problem will be solved. CZ springs have gone way down in quality and are all under sprung.

Hmm the only (yes ONLY) ammo fed to my CZ so far is winchester value packs. I've yet to have a single malfunction but maybe I'm lucky? I would suggest cleaning first springing second.

I've heard tell that many eastern european pistols are undersprung from the factory, or that their springs don't last.
That said, I've never had an extraction issue in over 1k rounds of WWB in my 75. I've had the thing lock open on an unexpended mag (bullet nose was bumping the slide release), but never a FTE. |

I have over 6,000 rounds through mine from countless manufacturers, 1 jam, and 3 FTF(that was the ammo). Check your extractor and the ammo!
