Every once in a while my CZ-75B, which I bought used, will fail to eject. It happens about once every couple hundred rounds. It's always the same type of jam, with the empty wedged between the top inside of the slide and the round feeding from the magazine, the cases essentially parallel. I also have an SP-01 and I have never had a problem with it, so I don't think it's just me. Any suggestions?

What ammo are you using?
WWB and Winchester cases can give certain CZ's fits because the extractor groove is not as deep. This, and the extractor design can cause issues with some pistols. You can either blow out the gunk behind the extractor with spray, or if it is really annoying, contact CZ-USA and get a new extractor. |

This was a regular factory WWB value pack round. It also occasionally happens with my own reloads which are mostly Winchester casings. You can take a file and make the notch on the extractor a bit deeper so it can engage the extractor groove of the Winchester cases, or ask CZ-USA if a new extractor will help. |

When I get a new to me/used firearm, usually the first thing I do is order new springs for it. No telling what condition they are in. You should probably do the same..... My CZ had this problem after about 2k rounds. Go with new wolff recoil spring and you will likely solve the problem. |

If it is surface hardened, it will break where you file it. A gun plumber hacked my extractor on a 1911 I owned. It broke the first time I used it. |

Get an extra power extractor spring:

Extra power extractor springs are available to correct extraction problems common in the CZ-75/85 series pistols - all calibers. Wolff springs are approximately 25% stronger than factory springs. quote] http://www.gunsprings.com/Semi-Auto%20Pistols/CZ/75%20Series/cID1/mID16/dID91 http://www.miossigunworks.com/on_line_catalog.html |

Well I was only able to fire 34 rounds over the weekend.
18 were my own 147gr. LFP reloads in mixed brass. 16 were WWB 115gr. FMJ. No malfunctions of any kind to report...hopefully I'll be able to put a substantial amount through soon to get real verification. |
