Having obtained four of these fine weapons -- 2 CZ's, a BE, & a Witness .45 -- I am more and more impressed by the quality that I never realized was there. However, I read in a book I got from CZ ("CZ 75: The Birth of a Legend") that the original expectation for longevity of the CZ was 5,000 rounds; with the redesign of the B model that expectation was increased to 8,000 with an actual longevity of 12,000 rounds. I am wondering how this measures up to other similar weapons on the market such as the Beretta 92's, Sig 220 series pistols, BHP's, Glocks, etc. I have been wondering if this is one reason these pistols are not as popular as some of these others.

First I've heard of that. I've yet to hear of anyone wearing one out, but then I've never seen anyone shoot them the way Chuck Taylor shoots that Glock 17, for example. ;)

I called CZ-USA last week and ordered a couple new internal and external recoil springs for the thing. Might as well replace them before anything goes south.

Hello. I don't know about official expected lifespans on the CZ-75 but am aware that there was a problem with slide stops breaking, which turned out to be due to undersprung recoil springs from the factory. I contacted Mike Eagleshield at CZ-USA a few years ago and he advised that some of the factory springs were way underpowered and when checked, did not meet factory specs.

I have not shot CZ-75's much with factory springs as I normally shoot safe but warmish loads in 9mm and had gone to a Wolff extra power spring as SOP years earlier. My notes are not complete but on one of my Pre-B CZ's, I have no less than 12K full-power loads w/o any parts replacements other than recoil springs. On another, the round count is roughly 9K with the same good luck.

I wonder if the "longevity" estimation in the book simply means between small parts failures?

In any event, the guns seem to still be going strong. Should there be any parts failures or catastrophic slide/frame failures, I'll post such here.

Best.

PS: I've left a post for Mr. Angus Hobdell at a CZ site asking for his experience as a competitor using CZ pistols and his observations on this matter. If and when he replies, I'll post his findings here.

Thanks to both of you for the replies. On page 46 in the book referenced earlier there is the statement: "...the main components of the handgun withstood a minimum of 12,000 shots fired" and reference is also made to the barrel, slide, and frame specifically. That does not rule out small parts breakage of course, and such may really be the bottom line of this discussion. As I now re-read the comments in the book, the year was 1980 when the durability requirement was raised, and this was before the B model was introduced. My bad! I will look forward to any information from Mr. Angus about this. Also, Mr. Erich, what is meant by "internal" and "external" recoil springs? I am taking my cue from you, Mr. Camp, and going to Wolff springs for sure any way we go here. Ray

I'm curious to hear of any response you might get, Steve.

RF, the RAMI has a recoil spring and then an internally spring-loaded guide-rod assembly. The internal recoil spring lives inside the guide-rod assembly, and the external recoil spring sits over the outside of it. I got my 2075 used (though not very used, so I figured that I should replace both recoil springs to ensure the gun is happy. I really like the gun. :)

Hi there all,

Here are my observations and I hope Mr. Twoguns chimes in as well.

Back over the summer, I purchased a '96 Manufactured CZ-75B from my local gun dealer that was "broken". The slide stop had sheared off and was laying inside the frame. I believe the gun was a "range rental" and that the owner had decided to get it fixed. Instead, he sold it to me sans slide stop and magazine.



[size=100:48tghwg4]This is the CZ in the condition I purchased it with the broken slidestop.[/size:48tghwg4]

A dear friend in Arizona sent me a new slide stop and recoil spring and the CZ-75B was quickly restored to shooting condition. From first hand experience, I did notice something peculiar.

First, the original slide stop was a 2 piece welded affair and it was evident that it had sheared off the slide stop pin at the "flat" of the latch. Whether this was from metalurgical failure or stress shear, I do not know.

The new slide stop was a one piece design and appeared more robust in appearance. I do not know if the new slide stop is investment cast or forged, but it really doesn't matter at this point as it works quite well.



[size=100:48tghwg4]Here is my CZ-75B in its "rehabbed" condition and it has turned into an excellent shooter.[/size:48tghwg4]

I do supect that longevity is measured by realiability between parts failure as opposed to "catatrophic" failure of the handgun, i.e. the frame cracking. It is fairly well known that the military measures the ability of a firearms lifespan by continuous testing until a part or system of the firearm fails to perform.

I have been asked by a couple of folks here to post pictures of the old slide stop and the new one and may today if I get a chance to dig it out of my parts box.

Based on my personal experience, I have become a big fan of the CZ-75B and like it a lot compared to other 9mm pistols of the same genre.

Hi Chris- What type of bumper is on your mag? Pretty cool, I'd like to order a few for my CZ's.

Howdy folks,

Thanks for sending the pm and posting the responses Mr. Steve. It is always best to try to get answers straight from the horses' mouths whenever possible.

Just to clarify a bit on some background for our members who might be wondering. Mr. Angus is the Captain of the CZ USA Shooting team and an excellent CZ smith. Mr. Matt is another member of the same team, and an excellent CZ smith as well. So you have two folks who have a very strong, hands on working and shooting experience with various CZ pistols responding to this issue.

When I have been on that site I often see where various members have fired 10, 20, 30, or 40 + Ks of rounds through their 75Bs without any parts failures at all. Sometimes I will read where a slide stop broke and had to be replaced. It appears to be common that many high volume shooters there, many who are competitive shooters as well, do tend to replace springs at some point as preventative maintenance.

When I had the pleasure of finally meeting Mr. Angusm to pick up my 75B he had worked his magic on and to purchase the SP-01 he had done the same to for me, the timing was such that I was able to pick up a new slide stop for a buddy of mine. I also discussed the issue of what pound springs he would suggest being installed into a used CZ75B. I was a bit surprised when Mr. Angus suggested using a lighter poundage spring, rather than going with a heavier one. He stated he always did this in his comp pistols, and to date with all the rounds fired through various pistols, he had yet to have a slide stop break. I followed his suggestion and got the suggested spring to send my buddy for his pistol, along with the slide stop he needed.

I also know from dealing with him that emails from Mr. Angus tend to be on the short side, as he is a typist using one finger of each hand, lol. Obviously he is a much more accomplished shooter and smith than a typist.

Mr. Gib, obviously I am not Mr. Chris, but I can answer your question for you sir. The mag is the 18 round mag that comes with the SP-01 in 9mm. That is the factory mag, and is what came with my newly purchased SP-01. They work fine, but since I might carry my SP-01 concealed at times too, I have also confirmed that the Mec-Gar 75B 16 rd 9mm mags work just fine in the SP-01 as well. Hope that helps. Yell if I can help further on that issue sir.

I am certainly not a Mr. Angus, Mr. Matt, or Mr. Steve, and will never try to claim to be. But in the short time I have been shaking hands with the CZ pistols, I have become more and more impressed with them. Most folks posting comments about their pistols on that forum do nothing short of rave over the accuracy, performance and durability of their weapons. More and more I am having to agree with those comments.

I fired my SP-01 and my 75B in 40 both quite a bit this past Saturday with my shooting buddy, Mr. John, out in the desert. I probably fired 400 more rounds through the SP-01 as part of its break-in. It was both boringly accurate and reliable, with no problems at all.

I managed to put another 73 rounds throught the 75B 40, wanting to see what kind of group I could get from 6 mags after working the SP-01 out. I would have fired more, but I did not want to have to draw down on Mr. John to get my 40 cal from him, lol. I was shooting from about 10 yards, standing two hand hold, and ended up with a group that would probably be covered with a silver dollar. I was impressed with myself, and even more impressed with the accuracy the 75B 40 gives me too. I sometimes have read folks commenting that the 40 round is just not inherently accurate. This pistol might change their mind, but to be honest I have never experienced an accuracy issue with any 40 cal pistol I have fired.

Personally I think these CZ pistols are built like a tank, and will give me more rounds down range than I may be able to put through them when all is said and done. Just my thoughts, but I am glad to hear that they are largely consistent with the folks I feel do know things - Mr. Angus, Mr. Matt, and Mr. Steve.

Hello. From Mr. Hobdell's reply I gathered that he shoots mostly lighter loads so I suspect that the lighter spring, particularly if the bbl has a comp hanging off of it is likely the way to go. When I discussed shooting warmish loads on a pretty regular basis, he suggested staying with the heavier springs or at least those rated to the 9mm factory standard 14 or 14.5-lb recoil springs. I've been using the 18.5-lb spring for several years now with no problems though I have been contacted by folks advising that this weight recoil spring simply didn't allow their pistol to function properly. As a rule, the 16.5-lb worked fine for them.

I do not know if it is still a problem, but at one time some of the factory standard CZ 9mm recoil springs were checked with some offering less than 10-lbs! This is during the time that complaints were rising about breaking slide stop levers.

Based on what I've personally seen and shot with the CZ-75 as well as the observations related by others, I feel pretty sure that the guns will run satisfactorily for a significantly greater number of shots fired than the book suggests. Such might in fact not be the case if one shoots warmer loads with a lighter than standard recoil spring, at least in my opinion.

The only other problem I've ever had with CZ-75 pistols was also spring-related, but not the recoil spring.


This particular CZ-75 9mm shot warmer loads accurately and reliably using the Wolff conventional 18.5-lb recoil spring. The only problem was that it would reliably be unreliable with a favored handload using a 124-gr. Hornady XTP over 6.0-gr. Unique! All of my other CZ's would feed and group nicely with this javelina-killing handload. Not this one, though! The top round waiting to be fed into the chamber would nose-dive when the gun was fired and refuse to feed. Chambering by hand was slick as a gut, but it would almost always jam when fired. To make a long story shorter, I ordered a few of the Wolff +5 and +10% extra power magazine springs: End of problem and it has not reared its head again with something around 1K rounds being fired. I could tell no difference between the +5% or +10%; both worked equally well. Just a thought I would mention it in case any of the folks here have experienced the same problem.

Best.

Hi there all,

Mr. Twoguns and Mr. Camp. Thank you both for your generous replies as you've added to my knowlege of the CZ 75 significantly!

Very interesting reply from Mr. Hobnell and I will share one last story about CZ small parts.

After getting my "rehabbed" CZ-75B shooting, I started having some failures to extract. I called CZUSA and was put in touch with their Head Gunsmith, Mr. Mike Eagleshield. When I explained the problem to him he simply told me to "remove the extractor and clean the extractor cut channel". I asked if I need to replace the extractor and he said "No, just remove the extractor and clean underneath it".

Taking the slide off of the frame, I removed the extractor pin, spring and extractor. Then, I took a Midway USA Polymer gunsmith pick and removed a black 1/8" ball of oily grime from the cut. I reassembled the pistol and took it to the shooting range. All signs of malfunctions had disappeared.

The jist of this is that I suspect CZ small parts are more robust than they are given credit for and that spring changes help extend their life with a regieme of maintainance as with any other handgun.

Twoguns- Thanks for the heads up on the mags. I'm getting my CZ75 in .40 out of lay away soon and wanted to know what mods Angus did with your .40 and if you'd do anything different? My CZ 75 9mm is s/a that Angus worked on and I am very happy with it. I am thinking of keeping this one s/a/ d/a and do sights and action work with his hammer and sear, maybe change the trigger to the SP-01 type. Any suggestions would be appreciated.

Thanks- Gib

The CZ 75B in .40 was my introduction to the world of CZs. If I ever had to sell my collections of CZs, it would be the last one sold ... and only if there was no other alternative.

Of all the .40s I've ever fired. the CZ 75B has been the softest shooting .40 I've encountered. As such, it was for the longest time, my most accurate CZ.

Howdy Mr. Gib,

I purchased my 40 in DA/SA as well. While I will carry it in SA mode 98% of the time, it is still a plus to me to have that additional option if ever needed for some reason.

My 75B came with the older, standard silver trigger. If yours has the black trigger, then it already has the SP-01 trigger. I added Trijicon nightsights to mine, and asked Mr. Angus to install the SP-01 trigger, his sear and hammer and do an action job for "carry" purposes. Many of the pistols he works on are done for other competitive shooters, so I simply requested a carry action job, as that is what I will use my CZ pistols for - carry and SD only. I have also added the factory rubber grips which I really like the fit and feel of.

I am very impressed and happy with the work Mr. Angus did on mine honestly. I am so happy with it, I am confident when (not if, as I know I will be getting others) I buy other CZ pistols, they will either come from his inventory with the same work requested, or they will end up at his business for him to work his magic on for me when he has the time. He knew I would want nightsights installed on my SP-01 he sold to me after working his magic. Mr. Angus was kind enough to simply get one with nightsights already on it to save me the additional expense of adding Trijicons afterwards.

He is a pleasure to deal with as you already know. If you need any parts, he would be the place I would start, and then the factory if he happens to be out of stock on something you need. On parts and bullet orders (only things I have purchased off his website) he gets the orders out very quickly too.

Hope this helps. If you have other questions, please feel free to shoot me a pm. I just don't want to hi-jack an excellent thread.

Mike and Twoguns- thanks for the input. Sorry to have hi jacked the thread but I think the hi praise the CZ gets from its owners says something about their reliability.

Howdy Mr. Gib,

No problems sir. I was more quilty than you were, so I just wanted to avoid doing it more.

All questions are welcome, so always feel free to start another thread or send me a pm whenever I can help out sir (tips my hat).

Wow! I am awed by the experience, friendliness, openness, and helpfulness of all of you whom I have enjoyed reading on this forum. And thank you all so much for all the information in this thread. I am ordering springs next for my CZ's and clones and will consider a .40 as my next CZ purchase. What is it called -- CZitis? I think I'm infected.

I am picking up an EAA Witness 9mm today. From Mr Camps and others positive writings about the CZ I thought I would try the less exspensive copy. I don't own any DA semi-auto's except for the Browning BDA 380. So this will be the first DA/SA pistol I'll have. I will post my findings after I spend a little range time with her. By the way, I'm just about out of Harley money.
