CZ75 recoil spring

[PushPuller]

Hi everyone, after years of viewing forums on here I'm finally posting my first thread.

So long story short I bought a CZ75b a couple months back and fell in love. Now iv got about 2500 rounds through it and know she's a keeper, so I'm starting to pick up spare parts. Iv however run into a bit of jam with the recoil spring of all things. Iv read that Wolff springs are the right length, but aren't the best fit around the guide rod. CZ customs springs seem to be the right diameter, but I hear that its common to have to trim the spring back to fit, which I would think would alter the weight of the spring.

Iv also been hearing a lot about using Browning Hi-Power springs.

Which springs have you guys used? or suggest using. Thanks in advance for the help as this is starting to get frustrating.

First and easiest upgrade is to one of Wolff's XP springs.

Easiest is to buy another factory spring.

Mess with the springs and you mess with the science. Springs are made for the weight of the slide and anticipated SAAMI spec ammunition. Aftermarket springs are made to make the aftermarket industry money.

BTW, I am looking into an aftermarket spring for an obsolete gun. Can't get a factory spring and so aftermarket it is.

I’d stick with a standard 14lb weight recoil spring for the CZ 75B, the Wolff part number is #53814, or just keep the stock spring.

[PushPuller]

I'd like to keep it as stock as possible, unfortunately CZs website refers you to CZ customs for parts (unless Iv just missed it).

An it seems as though doing a simple web search for a stock spring brings up only Wolff springs, or CZ customs. Perhaps I could contact a dealer and see if they have any extra.

Here is the link to CZ USA website for that part. You can buy from them but you need to create an account first.

I have a 75B, 75 pre-B, and a 75D PCR. I have found Wolff springs are tool long, and bind in the dust cover, so I only use CZ factory springs. I also stick with the factory, standard weight.

Another option is the CGW 14lb. “Grey” recoil spring per the link. Color coding the recoil spring by weight avoids confusion as to what spring you’re using.

Note the comment, “The factory spring weight for full size 9mm/40S&W is 16 pounds.” This conflicts with Wolff who states the standard spring weight for full size 9mm is 14 lbs. & 16 lbs for .40S&W. CGW states their spring fits all full size CZ’s (9mm/.40S&W/.45ACP).

I’d be inclined to stick with the “Grey” CGW 14lb spring for a 9mm 75B. I also appreciate their tech tip for choosing the correct weight spring, as follows;

“There are 2 methods for selecting the correct recoil spring. The most common method is based on the ejection distance of a fired case. Ideally, the case should land 6-8 feet from you stance. This method allows your CZ to achieve the correct slide velocity that is critical for extraction, ejection, feeding, and slide lock. The other method, for competition shooters, is how fast your sights re-align with the target.”

You won't need to fiddle with the recoil spring unless you also fiddle with the load you're using.
"...anticipated SAAMI spec ammunition..." CIP. It's a CZ. Not made in the U.S. CIP specs are slightly different than SAAMI.

[PushPuller]

Thanks for all the help. I think I'm going to buy the CGW 14lb grey spring, and the factory spring from CZ USA. I can always try both of them and whichever one performs better I'll install and keep the other one as a decent backup.

After playing with 75-based CZs, the best solution I've found is the Wolff-made Browning High Power recoil spring. The BHP spring has a smaller diameter (which fits the CZ guide rod more snuggly than the Wolff springs for the CZ), and is also available in a number of weights, including a variable rate spring. It's cheaper than springs bought from CZ. (I don't have direct experience with the recoil springs from Cajun Gun Works, but hear they're good, too.)

The springs offered by Wolff for the CZ seem to be springs originally designed for the Tanfoglio version of the CZ design, which use a larger diameter guide rod -- and that lets the recoil spring slide around a bit more as the slide recoils. (They work fine, but some folks are put off by the noise the can hear when manually cycling the slide.)

And Walt has given us the word on CZ springs.

[Fishbed77]

I recently purchased a surplus CZ75B (manufactured in 1993). I purchased and installed a factory-weight Wolff spring (which also came packaged with a new firing pin spring). There we no issues with installing the Wolff spring.

It has functioned perfectly through a few hundred rounds so far.

So, as was said above (Post #2), the easiest upgrade for a CZ is simply to buy and install the correct Wolff spring.

Back when I got mine, the Czech springs were of low repute and replacement was routine. Are they better now?

[Walt Sherrill]

The only springs that seemed to be an issue were the extractor springs (and for a short period in the mid '90s, some trigger springs.) The other springs -- recoil and hammer -- were fine. The recoil springs were typically a pound or two lighter than stated (i.e., 12 ilbs rather than 14 ibls.) but worked fine. The other springs (slide stop and the springs in the sear assembly and in the firing pin safety) were never a problem.

Yeah, but some of us believe that the "correct" wolff springs aren't the ones that Wolff lists for the CZ. I think the "correct" springs are the ones they list for the Browning Hi-Power.

That said, I agree that the Wolff "CZ" springs work fine, but they ARE larger (in diameter) than factory springs and don't fit the guide rod snugly. These larger-diameter springs tend to rub on the inside of the dust cover and frame. That doesn't bother me, and they won't cause problems over the long term, but it DOES bother some owners.

I agree, Walt. That's why I quoted your post.

I'm not really sure that the Wolff springs (or any of the springs mentioned) could be considered an UPGRADE.

The reason I quoted your response above (after I looked at reply #2, again) is that nobody had mentioned the BHP springs until I did.

Just about any of the springs, be they BHP springs from Wolff, CZ Factory springs (from CZ-USA), "CZ" springs from Wolff (which appear to be designed to fit the larger-diameter Tanfoglio guide rod), springs from Cajun Gun Works, or springs from the CZ Custom Shop will all work well -- and darned few of them will ever really NEED to be replaced.

I'm surprised that ISMI doesn't offer CZ springs -- as they offer springs for Glocks, S&W, H&K, etc.

The spring chosen will probably just boil down to the buyer's concern about aesthetics, costs, and expected turnaround times when he or she is ready to order.

Per the Wolff website their part number for the BHP recoil spring is #40717 and it notes that the Browning Hi-Power in 9mm has a 17 Lb. factory recoil spring.

CZ states that the factory OEM spring rate for the 9mm and .40S&W 75B is 16 lbs.

Cajun Gun Works color codes their recoil springs and recommends their “Grey” 14lb recoil spring for the full size 9mm CZ 75B. I’ve personally seen enough great examples of their gunsmith craftsmanship to convince me that these guys know CZ pistols better than the rest of us. And I really like their tech tip for selecting a recoil spring based on the ejection distance of a fired case, which says that ideally, the case should land 6-8 feet from you stance. Can’t argue with good common sense.

The stock spring still works fine in my 75B but I’m going to order a spare “Grey” 14 lb. CGW spring and perhaps do a little experimenting with the ejection distance.

Wolff offers the following in BHP springs:

• Stock No. 13137 - Recoil Calibration Pak: Contains 1 each of the above conventional recoil springs in 17, 18.5, 20 and 22 pounds. Three extra power firing pin springs are also included.

• Stock No. 13138 - Variable Calibration Pak: Contains 1 each of the above reduced power variable recoil springs in 10, 11, 12, 13, 14, 15 and 16 pounds. Three extra power firing pin springs are also included.

• Stock No. 14050 - Performance Pak: Contains 1 each 12 Lb. reduced power variable recoil spring, 18.5 Lb. extra power recoil spring, extra power firing pin spring and 26 Lb. reduced power hammer spring.

CZ, at one time, said the factory OEM springs were 14 lbs, but all of the springs we measured seldom exceeded 12 lbs when new.... never tried measuring them later. (That said, I now have a spring tester...)

I've used and prefer the variable rate springs... Wish you could buy a single weight rather than having to get the "calibration" packs.

But as I've written before, which spring you use is really a matter of individual choice -- as just about all of them will work, (regardless of who offers them) even with anemic ammo.

Here's a little update on my situation. I received my CGW spring yesterday and put it in to see if I could notice anything different so far. Felt recoil and action feels almost exactly as the stock spring. Casing placement was between 6 and 7 feet every time at about my 3:30-4:00. The stock spring was placing brass at about 8-8.5 feet at the 3:30 position.

All in all I'm pleased with both springs, but CGW is probably the route I'll take in the future. although I am debating buying the BHP spring just out of pure experimental curiosity.
