CZ 75B Omega trigger return spring: second breakage in new pistol

[Flintsky]

When the oficial CZ team from Czech Republic came here to an IPSC tournament, I asked them about replacement intervals for TRS, slide stops, if they break them and how often, etc. and I got a angry stare back, like "our guns never break"...

Yeah, they are kinda like the H&K of old. There is a clue when their competition models come with multiple replacement slide stops in the box(already assuming lots of broken stops). I knew a guy in the early 2000s who ran a 75b in competition, and he performed a full overhaul and spring replacement before each competition. I loved the ergonomics and mechanical accuracy of the classic CZs. They were very easy to shoot well. However, a broken slide stop or trigger return spring renders the pistol DRT until it can be repaired. My CZs were relatively low round count(under 10k rounds), when I started breaking slide stops, TRS, and extractors(even with proper chambering via loading from the magazine).

Do these problems extend to the newer designs like the P-07 and P-09?

No

Do snapcaps prevent breakages?

Omega trigger system parts are bigger-ish, and therefore (to my understanding) more robust - how much moreso, I dunno.

(Heard the Shadow2 TRS and slide stop are bigger too... )

These use a Sig type lockup so should not have the issue with slide stops
same with the 97b

@BLR might have some thoughts on spring choice and design.

I might not be looking hard enough, but I can't find a different Shadow2 TRS anywhere. Looks like the 75/85/p07/p09 all use the same part. I know nothing about springs, but it seems to me that they could use a larger diameter wire with fewer coils and perhaps get the same spring strength (pure conjecture on my part).

Embarrassingly weak. Thanks for the link.

Interesting, what do you mean by SIG-type lockup? How's the CZ75 different?
