Another CZ bites the dust...

[briang2ad]

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.

I agree this is very disappointing for sure. Yes most people will agree that the trigger return spring is the weak point in CZ DA/SA handguns. I have talked with people that have broken one,& I have shot a fair amount of rds out of mine and not broken one, so I guess its my luck. Now with that said the 3 CZs that I shoot the most have all been sent of to CGW and I assume the TRS has been replaced with one of there own springs. I guess I'm suggesting that if you have broken that many have you ever tried a CGW or other aftermarket spring ? If you just keep replacing it with a "stock" factory spring your fixing the immediate problem but not fixing the real problem at hand & that's a weak/crappy factory spring. That's my thoughts anyways. I hope you get it working/going your way. Keep us posted on how ya make out.

just kidding.

I've found all small pieces in CZ handguns to be a weak points using factory parts.
Changing them to CGW version fixed all my similar problems.

I have broken all three - shadow 2, stock, and CGW - its just a bad design. 

I'm getting to the point I don't trust these guns.  Too bad  - I'm a CZ guy.

LOL!

Seems like, maybe, a couple years ago I just went ahead and replaced the factory trigger return springs with the CGW reduced power TRS in my P07 and both P09s, just to be sure(??).

I probably replaced it in the steel framed P01 I converted to SAO.  Not sure about the CZ75 Compact. 

Seems like someone here (CGW??) recommended keeping the springs well oiled vs. running them dry.  OP, do you keep it oiled up (the TRS) or let it go?

I keep mine well oiled (drop of oil on it every time I clean it/lube it).

[briang2ad]

Thanks - I do lube and I have not shot this one much, so when I was dry firing it today it MAY have been a tad dry but definitely has oil residue.  Still it reflects an achilles heal for the whole line.  I dry fire the snot out of SIGs, HK, FNXs, etc.  NEVER have broken these.

I would agree that my HKs are built to a higher long-term durability standard and are more extensively tested. HKs are probably, on the whole, the most extensively-tested handguns available these days. You'll have to pry my 45C from my cold, dead mitts. 

But dangit, my CZs are so easy to shoot well....

Maybe if I leave one of my CZs and one of my HKs in a dark room alone overnight, with a little Barry White and a bottle of Courvoisier, they'll produce the perfect love child...

I FULLY agree.  But man, if your gun breaks in the middle of a fight, you are screwed.

Every other post you complain about a broken CZ trs. Why don't you just get rid of all of them and stick with your SIGS and whatever else you like??? Yeah I know some of you guys break the trs and I can't seem to duplicate what you are doing wrong because I just can't get one to break. My 75BD has 26,000 rnds  on it's original trs, PCR with 16,000 rnd and so on. I just can't break one.
Reliability my CZ's outperform my SIGS hands down. The CZ's never choke but every one of the three P229 variants I own has an annoying feed stoppage every few hundred rnds While the CZ's never choke on anything. HK's have the sorriest trigger I have ever experienced and good luck finding spare mags for the FNX in any quantity let alone at a reasonable price.

   Aside from a bad batch of parts or an odd bad part in a batch of good parts, my bet is that high volume dry fire practice is a significant contributor to a broken TRS. In contrast to live fire, with dry fire, the only limitation to trigger pulls over time is the available time and your finger getting tired.

   I saw a guy build a contraption hooked up to an electric motor once to pull the trigger for him to smooth out the action. Shortly after hooking his new CZ up to it, the TRS broke. The machine was running no faster than you could pull the trigger manually, but it never stopped. I assume that in some cases the spring heats up to a point and then fails.

This seams to be in part why some folks have a practice pistol and another match pistol of the same type and configuration.

I have spent enough time with CZ 75 variants to find some of their weaker points. Ill bet that if i had spent an equal amount of time with another platform i would find some of their weaker points as well.

Is there an after-market spring available that has more durability?

I agree. High volume dry fire and the coat hanger effect which causes heating of the spring are likely causes. I prefer live fire practice so I don't do any dry fire at all. The thing is these guys dry fire practicing actually have no idea how many times they are pulling the trigger so over time some of these springs may have been cycled tens of thousands of times in addition to what ever live fire they've been subjected to.

   I am aware of a number of different TRS options. The question is, how dose one establish that one is less likely to fail than another. In the end we are all working form some personal experiences and different instances of other CZ owners exsperinces of which we do not know all of the details.

Also agreed. I think that if you are someone who does a lot of dry fire practice, it's probably a good idea to pro-actively be swapping out springs on a more frequent basis.
