CZ 75 problems

    Let me just tell y'all what happenned when I shot my first 9mm pistol today, a NIB CZ-75 made in 1995.

    I started by loading up two magazines of 115gr WWB ball ammo and was looking forward to experiencing the legendary CZ accuracy and reliability. The problem was that I got the first and not the second. Shooting at 25 yards in a standing unsupported position, I shot a 6.5" group with my first 15rd magazine but when I loaded the second magazine, the 6th round resulted in a failure to extract (the slide was locked backwards and half the empty brass cartridge was hanging out of the chamber). I thought that this simply meant that the gun needed to be broken in and I loaded up another 30rds in my two magazines while hoping for the best.

    However, i ended up being disappointed when my second magazine gave me another FTE! :fire: At this point, another shooter in an adjacent lane noticed my consussive cursing and suggested that I should replace my factory recoil spring with one rated for a lower poundage. It is my understanding that the factory recoil springs are rated for 13 or 14lbs and my shooting neighbour let me try out a 12lb spring from his toolkit.

    Four magazines containing a total of 60rds later, I experienced two stovepipes with two different magazine. :fire: At this stage, my newfound friend took out a recoil spring rated for 15lbs and suggested that I try that out instead. Consequently, I noticed that the recoil felt heavier, racking the slide took more effort but my last 100rounds of WWB was fired reliably without any hiccups from my pistol.

    Can anyone here help me out? What's happenning with my pistol? Why did it not work accurately out of the box? I thought that all CZ pistols were tested before they left the factory?

    Sorry about your CZ experience:(
    In all my CZs, the factory recoil spring works just fine, maybe a bit light. The older pistols did have weak spring issues, the extractor spring being one of them, I would change it out as well...
    A call to CZ USA may help also.

    It dont sound like limp wristing, but it could cause what your seeing.

    Stock recoil spring is 16lbs. I would give CZ usa a call or start by replacing all your springs.

    I use to have a 75b military that was made in 1996.It started to develop extraction problems. I ordered a new extractor and replaced it and the problem went away. The newer extractor also had a larger claw then the original. Order an extra power spring from wolf and if that doesn't fix the problem order a new extractor. The stock recoil springs are 14lbs. by the way.

    A NIB '95 production gun?

    Honestly, I'm doubting the NIB part on an 18 year old gun. I suspect you have worn out springs. Get some from CZ or Wolff.

    "I use to have a 75b military that was made in 1996"

    I still have mine. What a great gun at a tremendous price back then. That's all I know about the -75B.

    "I thought that this simply meant that the gun needed to be broken in"

    Did you clean it and lube it before you shot it? Were these the original factory mags? And lastly, quite a few folks have had trouble with certain batches of 9mm WWB. Have you tried other ammo brands yet?

    Try some different ammo. WWB isn't exactly high power stuff.

    Part of me wonders if this is just an issue of "break in period". :confused:

    If his 15lb spring worked, get one and take it back out.

    Am based overseas.

    Thanks for all the replies thus far but there are a couple of things that need clarification.

    1) I am based in South East Asia and won't be able to access the help provided by CZ-USA. My contract with the local branch of a US MNC will not end for another four years and my next home leave is not scheduled for another 10 months.
    2) I bought the CZ-75 (its not a B model) from a local gun dealer and am 100% sure that it is NIB. When I got it, the gun still had the original preservative grease on it and the inside of the barrel still had the characteristic "insect turds" within which is basically dried grease from the factory.
    3) Naturally, my magazines are the original factory fresh 15 rounders that came with the gun.
    4) Lastly, the recoil spring that I put into the pistol in place of the factory spring comes from Wilson Combat and appears to be made at least 10 years ago. As stated earlier, the new spring is one pound "stronger" than the factory spring at 15lbs and oddly enough is 5mm LONGER than the factory spring.

    In any case, the gun is now harder to rack but with the Wilson Combat recoil spring, my last 100 rounds of WWB were jam free. Can I assume that my problem is solved. Is 100 rounds enough proof of reliability?

    Lastly, can anyone here guide me to an on-line graphical tutorial on how to replace the critical springs (apart from the main recoil spring) in the CZ-75's upper receiver?

    WWB is not that weak when compared to the other common range ammo, see some examples below:

    Federal Champion 1120 fps
    Tula 1150 fps
    Most factory re-manufactured 1140 fps (locally)
    Remington 1145fps
    CCI Blazer 1145 fps
    PMC 1150 fps
    Brown Bear 1180 fps
    Independence 5250 - 1150 fps
    S&B 1300 fps
    WWB 1190 fps

    CZ's accuracy is certainly above average. Their reliability is an internet myth. They are one of the worst performing guns on the market in this regard. This is one of many reasons you will not see any in the holsters of LE or anything but a few 3rd world militaries.

    If you don't belive me do a few internet searches of CZ malfunctions. You will find more posts for problems just like this than any other gun. Pretty telling when you consider CZ only sells a tiny fraction of the guns sold by any other manufacturer.

    This is a common problem. Let a gunsmith replace every spring in the gun and in all factory magazines. While he has it you might as well have the trigger worked on at the same time. When finished you will have a great range gun that will likely shoot as well as anything. But there is nothing CZ makes I'd trust my life with.

    For the 9mm full-size gun, stock recoil spring weight is 14 lbs. It's 16 lbs for the .40 model, and 17 lbs. for both the 9mm and .40 compact models. I've never noticed much difference in performance regardless of the weight used, but prefer the lighter springs because they may the slide easier to rack.

    The problems described seem to have more than one cause: early lock back of the slide could be due a bent (or out-of-position) slide stop spring, a slightly oversize slide stop (being hit by rounds as they feed or get ready to feed), or out of spec ammo). I had that happen with my 85 Combat when new, many years ago: you could see where the jacketed round was bumping the nub on the slide stop. A few light passes with a file fixed that.

    The failures to properly extract or eject may be due to a weak extractor spring -- CZ had weaker extractor springs in the older models. CZ has upgraded them, and you can also get them from Wolff Springs. If it wasn't NIB, there may be junk behind the extractor.

    If your gun was truly NIB, you should call CZ-USA, as suggested, and see what they have to say. You can email them. You sound frustrated, but none of this is particularly serious -- and many folks often have problems with a NEW GUN, until it is broken in, and they are more familiar with the gun.

    You'll find one in my holster on duty. Last time I checked, Texas wasn't a third world anything.

    Because random google searches on the internet are a great basis for anything. I shoot my CZ-75B in IDPA all the time as well as use it for work, qualifications and training. Never had a problem with it.

    That's not to say that there aren't CZs with problems out there. My CZ-40P never ran well no matter what I did to it. But CZ-75Bs that people haven't screwed with, or aren't trying their new handload in, work like clocks.

    Interestingly enough, at the last IDPA match I saw a guys <insert popular brand> 1911 mag spit it's follower through the feed lips. He told me he bought them because the chatter on the internet said they were good mags. Take internet chatter with a large grain of salt.

    After all, my Glock should have shot me by now, my AR-15 can't kill anything bigger than rabbits and my 1911 cost $1500. ... according to the internet.

    Tired_and_hungry, if the gun really has been in packing grease for 18 years (you lucky dog), there's a good chance that what you are experiencing is because some dried up nasty has gotten behind the extractor. Failing to pull a case out of the chamber is a good indicator that the extractor is jumping off of the rim. Punch out the extractor pin to dismount the extractor then clean up in there real well.

    Hmm. I guess that's why Ruger has never had a lot of LE or military business, huh? Too unreliable? S&W hasn't sold many guns to military units around the world in the last 25-30 years, either. Guess they're just too unreliable, too?

    You may not like CZs, and I can understand that, as everyone has different tastes and likes with handguns. Lots of folks don't like Glocks, either. That said, your assertion, above, is basically fantasy (like much of what we read on the internet), based on your dislikes and not on facts.

    Despite CZ's long history of firearm production, it was absorbed by the Communist economic monolith after WWII; until the fall of the Soviet Union, CZ was a government run business. (They made a lot of motorcycles and refrigerators, among other things.) When the Communist Bloc finally fell, CZ had to start all over as a capitalist business, and had to get its own funding -- not an easy thing to do at the time. In that sense, it's had to act like any other small business enterprise, basically starting over from scratch. I'm surprised they even survived. Most of the car makers in the old Communist Bloc just disappeared...

    CZ can't compete with the big gun makers for LE or military business. It's a relatively small company without the deep pockets of Glock, S&W, SIG, Beretta, etc. It's also unlikely that CZ will set up a factory here in the US any time soon, either -- something required for many US LE and Military contracts. CZ is just starting to get a number of military contracts.

    If you have some FACTUAL data or information to substantiate your claims, above (about why CZ hasn't sold more to LE and Military purchasers), share them with us -- but please don't give us your attitudes and expect us to treat them as facts.

    Click, I would think you would be more right about the ejector rather than a spring issue, but not sure why the 100 rounds with Wilson spring ran flawless, . . . unless through the firing process, what was lodged no longer is.

    It's entirely possible that shooting the gun broke down what ever was gumming it up,

    Yes. I would be interested in the OP taking it back to the range with the spring that came with the gun and seeing how it does now.

    Members of armed forces and police of leading nations do not like their pants to keep falling off and suspenders aren't really that comfortable either. The CZ75 is product of the 1970s and when compared to modern designs like the Caracal it really shows its age. My full size .45auto unladen with magazine in place comes in at <26oz. My advice would be to eat, rest and trade that gun for something like: Glock, Caracal, M&P or XD.

    Israel isn't exactly 3rd World, either, and they used a ton of them.

    CZ may have changed things over the years, like how they pack the gun. All mine came with loads of oil on everything, no grease.
