I registered to the czforum but it wouldnt let me post so I'll try this here.
I put 200 rounds through my cz today and had a few jams. one stove pipe and three ftf in which the slide stoped about a quarter of an inch from going into battery. And several times when I hit the mag release to load the gun I would get a ftf simular too one above. Ammo was a box of UMC, box of Win white box, box of reloads (medium charge of bullseye on 115grs fmj), and a box of factory remanufactured and experienced problems with all but the reloads. This is a new gun and this was my second outing with it and has had total of 286 rounds through it as of today.
Any CZers care to help out?

Stupid question, but a friend of mine who should know better had this problem: did you clean the gun before you shot it? New guns often come caked in grease which can cause all sorts of problems until you clean it out. Oil on the feed ramp, in the chamber or in the barrel are generally bad things unless the gun is being put in storage.
 
Thanks.
I gave it a healthy dose of brake parts cleaner and a good scrubing the day I bought it so I dont think thats an issue.
 
Does the gun seem to have a preference for a particular magazine? I'm thinking either weak spring or bent feed lips if it does.

Oh yeah, also check for burrs on the underside of the slide. I had a beretta with that problem once. Every time the slide cycled, it would catch on the top round in the magazine on the return stroke.
 
Got a Dremel tool.
I would polish the feed ramp and chamber as a starting point.
While you have the gun apart check the extractor (with my old eyes I'd use a magnifying glass) and the extractor spring.
If that doesn't solve the problem I'd try a new recoil spring that is rated at least 2lbs heavier than the one that comes with the gun.
The recoil spring is a cheap fix and if it works the stock recoil spring will probably work OK after a few hundred rounds through the gun.

Unless you're a gunsmith, keep the dremel AWAY from new guns! If there's a problem with a new gun, let the factory fix it before it gets the bubba treatment.

I'm not sure how a CZ75B operates when dry, but mine works fantastic when cleaned and lubed with a light coat of CLP. If you're running it dry, run a CLP-moistened q-tip along the friction points and give it another shot.

Since it sounds like there may be something physically wrong with that many failures, if the pistol still exhibits problems, I'd suggest checking on having a proper smith (hopefully under warranty-like coverage) take care of that.

For reference, I've shot hundreds of WWB FMJs and Speer JHPs through my totally stock CZ75B without one failure, so there's definitely something wrong with yours.
 
Today I gave it a brake parts cleaner bath to get it completly degreased and then gave it a light coat of breakfree clp and took it back to the range with 100 rds of UMC which is all I have left .
I loaded up one mag and shot it with no problems. I then loaded the same mag again and when I hit the slide resease it failed to feed the first round and had another ftf half way through the mag. I then stuck my finger in the ejection port and wiped away the carbon on the feed ramp and breechface and loaded the same mag again and it shot fine. Then i switched mags and repeated the process and got the same result. As long as I wiped away the carbon on the feedramp and breechface between mags it works fine.
I'm starting to think that the UMC is just too dirty since I think the problems I had yesterday didnt show up until I start shooting the stuff and the reloads that I didnt have problems with were all gone by that time.

But as dirty as it may be, should'nt it be reasonable to expect the gun to last a little longer then 16 rounds before getting too fouled up to work?
 
You’ve got a QC issue, time to call CZ USA. I have three CZ pistols including a 75B that have also performed flawlessly out of the box.

The best time to call is around 2 PM CST. Ask to speak to a smith. When I had issues with two of my CZ rifles they were prompt and professional. They fixed the problems the first time in reasonable time. I can recommend CZ cs.
 
Hey vzenmn, I am getting similar probems with my 75bd that I bought used, but in very good condition.

I don't get the stovepipe issue anymore, could of been related to cleaning out the extractor spring area.

I still get the FTF issue, can't narrow it down to any particular mag or ammo, or even how full the mag is. Pretty aggravating to say the least.

I just got a wolf 14lb recoil (feels stronger than the stock 14) and 5% mag springs. I haven't been to the range yet, but with the stronger mag springs, snap-caps get pushed too high and get stuck at the top of the barrel. Maybe it will be different with real ammo.

Next time I go the range, I'll try it with just the new recoil spring and possible change to the stronger mag springs if I still have the problem.
 
Call Mike Eagleshield at CZ-USA, 1-800-955-4486. BTW, I don't remember your screen name coming across at czforum.com, when did you try to register? It takes a little while with Yuko running things.

I used mohawk600 as my screenname in the czforums. Every time I click new topic or post reply a screen comes up asking me to log in but it wont let me log in.

For a while now I have been trying to get the extractor apart but the pin is in there tight. I figured since I have been using the snapcaps that came with the gun alot that there might be some plastic that got sheered of them and got log in the extractor somewhere. I called CZ today but they're closed until the middle of next week. I think while I'm getting my oil changed at wallyworld tomorrow i'll pick me up a win value pack and see if my UMC ammo theory checks out.
 
Give it a whirl. The parts are tight, supposed to be.
I checked, that screenname hasn't floated through the membership base yet. If that was recent, hang on, Yuko is sloooooow.
 
Put 100 rds of win value pack through today and only got one ftf and loaded smoothly when the slide release was hit. Way better but I'm still a little uneasy. I'll give cz a call and see if I can get a new extractor or something. From what I have been reading the factory springs seem to have a tendency to become weak. Could that might be the cause?

P.S This Cz is scary freaking accurate with win ammo. I was getting better 25yard groups offhand with it then I was getting with my Security Six off the bench. And 5rd groups at 50 yards from a bench averaged around 7 inches with one being an 3 1/2 inch. :what:

I've got two CZ-75B's - one 9mm and one 40 and both are scary accurate with any ammo except wolf and then with 5 out of 6 of them (wolf QC sucks - I've learned to live with the occassional outlier).

My CZ-75's outshoot my Smiths, Kimber and Sigs easily. The only auto that outshoots my CZ's in my hands are my S&W 1911 Target and then just barely and only with my handloads (8.6 grs AA#5, WLP primer, under a 230gr FMJ RN bullet).

CZ-75 is 2nd only to Sig for sheer reliability in my opinion. Mine go/went bang every time except once. Trigger bound up on the 40 for some reason. Replaced the plastic trigger with the metal one and no more problems.

Vzenn, I think you just won the CZ lottery and got the rare bad one. Sucks to be sure but don't give up on CZ they make great handguns and great rifles (got two of those too).
 
Let CZ Fix It

I bought my 75B in June and fed it the same Remington and Winchester white box and Value-Pak ammo you did with ZERO problems. I also feed mine 124gr FMJ 1075 reloads. It should not have had all those problems if it was cleaned and lubed.
They are all light loads (1050+/-) while your reloads might have been a little heavier loads. Maybe it is the spring. Feed Failures using the slide stop to feed the first round sort of reinforces that.
Before I replaced springs or polished anything, I'd talk to CZ on the phone, and expect them to provide a shipping label (on-line) for a look-see.

P.S. It took several days before Armoredman gave me a nice welcome to the CZ Forum.

I bought a new CZ75b, 9mm a couple of months ago. Mine had a couple of stovepipes and the slide would lock open at random times. I cleaned the entire extractor blade from back to front with Gun Scrub, then added a drop of oil. That cured the stovepipe problem. I called Mike Eagleshield at CZ and he sent me a new slide stop and slide stop spring to correct the slide stop issue. I've since fired more than 500rds. of various types of ammo, including hollow points, without a single hiccup.

I've heard others say that 95% of CZ problems are spring related. Don't lose faith. I'm sure CZ's customer service will help get your gun working the way it's supposed to. And yes, these guns are scary accurate. The CZ is quickly becoming my favorite. Good luck! and keep us posted

Its not just CZ. Every single brand new gun I bought or was given has had to go back to the factory for repair. A mossberg 500 that I got for christmas 8 years ago would fire when you when you closed the action without pulling on the trigger:what: and there is an one inch size hole in my dads ceiling to prove it :what::what::eek:(my dad it not me), my P95 had the sear spring installed incorrectly causing the thing to lock up when I was putting the slide back on the frame, a blackhawk that had the hammer plunger hole drilled in the wrong place causing two hammer plungers to break, and now this.

And on the other hand I have a few old guns I bought or was given to me in well the hell used condition with little bluing left that have never failed in the hundreds apon hundreds of rounds I have put through them.

Its starting to seem like there is something to be learned here doesn't it?
 
I took my CZ75b out to the range last sunday after three range trips and about 1000 rounds cycled without cleaning it. The feedramp was coal black and I still cycled 200 trouble free FMJ rounds through it. It's hard to imagine that your issue springs solely from dirty ammo though anything's possible. Sorry bout your bad luck with new firearms by the way, that is tough.
 
I put two mags of that UMC through my P95 today and it was jam city. Several stovepipes and FTFs in both Mec- Gar mags. A few times it didn't even strip the next round from the mag. It was like the slide just went far enough to eject the spent casing but not far enough for the allow the the slide to catch on the rim of the shell in the mag. The empties also just fell at my feet so I am thinking that this ammo is loaded too light as well as dirty.

The ammo was bought at Wal-mart and is the 250 rd mega pack and I think the lot number is D29 0B10.
Does anyone have this stuff and can you tell me how it works in your guns?

vzenmn: Is it possible you're limp wristing your auto handguns?

I ask because my 9mm CZ has acted as you describe on occasion but only when my wife shoots it. When she thinks about it and doesn't limp wrist it, it behaves properly and has never failed when I am firing it.
 
You likely have a lemon that needs to go back to CZ USA. A 75B isn't some 1911, they should run flawlessly from round one.
 
Try "slingshotting" the slide instead of using the slide release for awhile. Sometimes new mags need to be used a little before they smooth out and loosen up.

Also make sure you keep your wrist locked while you're shooting.
 
rem umc

I just shot 6 rounds of remington umc thru my 38 it does seam to be pretty dirty after only 6 rounds.This is the first I have ever used it.I had bought it about 2 months ago and after reading your review I went out and poped off a few rounds.
