I know, this is an old thread but notice today I can press my firing pin all the way to the point it's protruding out the breech face without depressing the safety block. I emailed cz about it.

They ended up calling me, they stated this is not normal and is a safety issue. They sent me a shipping label within the hour I got off the phone with them. I sent it out and a month later I got it back fixed.

Defeated..??  :o

So within the last couple of months, I've learned that there's an evident issue with the EVO 3's and out of battery discharges (OOBD). Without making this too long, turns out that the only "ONE" passive safety feature this platform has is defective on a significant number of EVO 3's. So before making arguments and assumptions I went ahead and checked my bolt.

As you can clearly see, with the firing pin safety block not being pressed allows the firing pin to protrude, which confirms that either the bolt or safety block is out of spec. I contacted a good friend of mine which also owns an EVO 3 and after testing his, the issue is also evident on his platform as well....
To say the least, CZ will be hearing from us but more troubling is why does it seems that CZ is unaware of this issue, when so many people are clearly complaining and even flooding social media?? Even more troubling is why isn't there a recall since it's a safety issue?
I hope CZ peeks in these forums, I'd love to hear their take on this..

Edit.. for some reason my image won't show

I invested in the nexus firing pin block, i had a little protrusion of my pin with the factory safety block plus it was getting deformed. Its well worth the $45. I think I'll get their replacement recoil spring assembly next, I changed out my factory spring around 8500 rounds, it was starting to feel abit light and this 2nd factory soring has got atleast 6k on it and i been using some pretty hot loaded 124grs that extra 25% spring strength will help a good bit , just like a 1911 or cz 75 you gotta tune your springs to your preferred loadouts especially shooting hot +p ranges

Thx. For the heads up.. It's frustrating & disappointing that this unit doesn't have more than 100rds... I'll definitely consider the nexus firing pin block..
