Another CZ bites the dust...

[Earl Keese]

Ok so no true list of spares that need to be commonly replaced but maybe keep a spare set of springs on hand.

Now, which springs? Or is there a kit that covers it?

Spares:
Trigger return spring
extractor and spring
Sear spring
Firing pin block lifter spring
Recoil springs
Firing pin retaining pin
This is off the top of may head, someone else may have additional suggestions. If you're like briang2ad, buy a couple dozen trigger return springs. Or, if you upgrade with Cajun or CZ parts, you'll likely have all the spares you'll ever need.

[briang2ad]

If you have an omega get a couple ejector springs. You will drop them.

I have broken CGW springs but they do last longer than stock.

I believe the most often suggested spare parts (which may not be needed for thousands of rounds) are:
1. trigger return spring
2. extractor spring
3. extractor
4. firing pin retaining pin (get more than one)
5. recoil spring

That's for people who just shoot, clean and lube their pistols.

If you are one of those people who take the gun completely apart now and then, you'll want some of the smaller, easy to lose springs and parts and a free floating trigger pin from CGW (makes it easy to remove the trigger and trigger bar.

The little springs are the sear spring, the firing pin block lifting arm spring, the firing pin block return spring, the springs that push the safety detent in the frame against the safety (if it's a safety model pistol).

Have you managed to break any of the red painted TRS, that started showing up in factory CZs around a year ago? I am still curious if there was any change to the spring on the red ones.

. I believe the one I broke was one of these but it was in there a while and seemed less red than I thought when I took it out.  I DID replace it with a new version.  These actually add to the pull weight.  I think they will last longer but don’t fix the problem.

speaking of the color of the TRS, on my (made in 2017) my 75 B, does not have a colored spring.

now, my (made in 2020) 97B, does have a red spring...

both guns were bought brand new at the LGS.

all i do know is, that i put a drop of oil on the TRS, and the sear spring, each time i clean my guns, which that is, after every range visit. no matter how many rounds put thru either gun. lately due to the ammo shortage, that is only about 50 rounds per gun.

My young P01 Omega just broke its TRS.  I am really kinda down on CZs to the point I don't trust them like SIGs and HKs and even my new FNX9.  I have broken a myriad of TRS on my CZs and it just happens WAY too often.  I know 5 people will now repsond and say they've fired 10,000 rounds through their 8 CZs each with no TRS breaking. 

I know different.  The TRS in the CZ IS a known design flaw (I've even had someone tell me that from a prominent CZ shop) and I'm really not happy with CZs.  I broke 7-8 TRS in one gun alone, and this P01 has not seen more than 600 rounds and moderate dry firing.  This is ridiculous.  They shoot so darn well and are otherwise reliable.

Replace it with a CZ custom or Cajun part also a good idea to change the Firing pin retaining pin. The idea of changing those parts are like changing the tires or oil on your car. I prefer that these small parts are flawed vs the frame, slide, and barrel. Would rather have to change strut, headlight, or cheap fuse in a car vs the motor or transmission. If you want a flawless stock CZ the p01 NATO might be what you are searching for that thing has more R&D than any civilian can conduct. Have a great day.

I don't know which gun manufacturer is putting out firearms with bad barrels, slides, or frames.  "A flawless stock CZ P01 "NATO" is an interesting term.  The standard P01 has the same flawed TRS as the Omega.  I'd rather have a more durable TRS that you find on most other guns that can withstand thousands of dry fires and thousands of rounds - maybe tens of thousands, than a TRS that needs replacing every 5000.  Some have broken them with 1-2000 rounds. 

As already stated, a CGW TRS will likely increase life of the spring, but they do break.  I've broken a few. 

BTW - the fact that NATO approved a stock number to the P01 doesn't really imply much.  I doubt any more R&D went into the P01 than say the SP 2022. 

I've heard of folks replacing the TRS without pulling the FCG - I guess it may be doable, but not trivial.  on the "stock P01" to replace the TRS, you have to pull the FCG which is NON-trivial.  It is easier to install a short reset kit in a SIG than replace the TRS in a CZ. 

I think the P01 is a great design - accurate, reliable, but has a flaw - shared by all CZ hammer guns - the TRS.  I still like them, but this one problem is a PITA.

Hipoint pistols are awful guns from stock. The first series of sig p365 was a crap gun, and the Remington r51 pistol that was also garbage. The sig p320 cant pass a drop test without going off. The original shadow 2 had frames cracking now that I'm listing guns. Those are the major flaws I would compare a CZ p01 nato too. Just my opinion, I am not a squad officer like Larry Vickers or Mike from Garand Thumb. But the trigger return spring breaking occasionally and its and easy and quick fix doesnt seem like a problem to me. HK usp, Sig p226, and glock is more comparable to a NATO P01. Then there is this thing about running a steel guide rod in an aluminum frame and that it cause premature wear. Just my opinion. Happy holidays.

Garbage with known problems is a different issue.  I DO agree that a good comparison is the HK P30, USP, P228/9, P226, and I would add PX4, FNX9, etc.  We live in a day and age when there are boatloads of VERY reliable, accurate, and durable guns.

I will also assume when you say "P01 NATO" you are referring to the standard P01 with non-Omega controls. 

My point is that this very inexpensive part is a sort of Achilles heal, and it can only be helped, but not solved with an aftermarket part - yes, it only cost $7, but it renders the gun almost useless (you have to manually reset the trigger).  If you are in the middle of harms way, you're likely toast.  If you keep track and replace regularly, it may never be an issue.  But unlike say a Beretta 92 series locking block, it doesn't have to be replaced at say 15,000 rounds or the roll pin on a SIG German model at 5,000 and you KNOW you are GTG until that time. 

The CZ hammer gun TRS - common to all not just the P01  - will fail at some random point.  I just watched a video of a fairly good reviewer who ran his P01 Omega for 1000 rounds with some dry fire also, and his TRS broke.  Again, I've broken many.  It does not take abuse to break them. 

A gunsmith from a prominent shop told me it is a "design flaw".  I believe him to be correct after dealing with the 75 design and reading about it for 30 years. 

Now to the "NATO" model.  The decocker on this gun is fairly complex.  It is not an easy fix for the average gun owner or even armorer.  Getting the sear cage into and out of that gun is not easy.  Can the experienced gun enthusiast do it with practice and time on his hands?  Yes.  But it is MUCH more complex than the Omega version - and why CZ made the Omega.  I owned a P01 and ditched it and later got an Omega mostly because of this.

Still, stripping an HK or a SIG is trivial compared to the standard P01.  I can dry fire a P30, SIG P228/226, PX4, etc. etc. with virtually no fear of breaking the gun.  I always realize the real possibility of breaking the gun with a CZ 75 system because of the TRS.

Do I carry the P01?  Yes, on occasion.  DO I shoot it as good or better than other guns?  Yes.  Is it otherwise just as reliable and durable?  Yes.  It also has several other features that make it very attractive. 

(If I had to run out the door with ONE handgun to be dealt with and carried for the rest of my days, as much as I like it, it would not be a CZ at this point - because of this one problem).

So... why do I raise the point? 

Because most people don't realize this problem - especially new or first time gun owners, and they don't have the resources to own more than one good carry gun - and I think they need to weigh this in the mix. 

Also, dry firing must now become a much more regular part of an individuals training with ammo prices having become prohibitive because of cost.  (Range ammo is now 60 cents a round).  It also likely should have been used more than most shooters believe.  And... more extensive dry firing increases the likelihood of a TRS breakage). 

There is a method to this madness.

No, my logic is that the trs is small service part and it's better than having other major flaws. Like slides breaking and ect. Another pistol having issues is the M9's. The pistols the army first acquired had slides breaking and many other guns have some weakness and strength as well, the M9 was later improved and fixed that major problem. Again I understand all weapons have some kind of flaw but some are more serious than other like the gun actually destroying itself.

The original poster mentioned that he would not choose a CZ as a first choice if he had to leave in a SHTF situation. I wouldn't either, I agree. I would take and AR. A pistol of any kind would not be my first choice. I love CZ and they are some of the most copied and manufactured products in the world. They shoot very well can last a long time and I will continue to purchase their products as they evolve.

That other info in the video is just something I added. A friend send it to me and thought I was interesting.

This is just my opinion.

   While i beveled otherwise for a long time, replacing the TRS and changing Triggers without removing the Sear Cage is rather straight forward and quick in CZ 75 variants, once you get the hang of it. Once the Trigger Pin is out, the front of the Trigger Bar can be raised up high enough to remove the Trigger to Trigger bar connecting pin. Once this is accomplished the new TRS can be retained in the Trigger by a salve pin and then reinstalled.

If you are interested, i have some pictures from a post that i have not gotten around to finishing yet on the subject.
