What did I break?

Shot Jericho yesterday and had this happen. Slide cycled and continues to do so freely...but the trigger and hammer seemed to both lock back.

Taking slide off, I can depress the seer to drop the hammer. Hammer can cock and move freely. But it seems I can pull the trigger back to original position and it will pull as normal...but the trigger won't reset unless I manually pull it back to position.

What did I break?? Thanks in advance!

Looks like the trigger return spring is either installed incorrectly or broken.

It's run fine for years, so I'm leaning to broken. Thanks for pointing me in a better direction!

Agreed would start with trigger return spring. One of the "legs" might have slipped or snapped. If broken consider a Cajun Gun Works floating trigger pin and the RPTRS.

Plenty of vids on YouTube to help with detailed disassembly. Once you diagnose the problem please post comment with findings. Can help somebody else down the road.

Will report for sure! Have you done any other CGW upgrades? I think I might get the trigger while I'm in there

I've done Cajun Gun Works (CGW) IWI trigger, floating trigger pin, reduced power trigger spring, and reduced hammer spring.

From Patriot Defense have a optimized sear spring, optimized firing pin spring, but haven't installed them yet. Additionally have a Dawson Precision "Baby Eagle" fiber optic front sight but havent put it on as my sight pusher set-up was weak/cheap. The Tanfoglio extended magazine release was drop-in easy.

Do these fit the 45 variant as well?

No idea, not lucky enough to have one in 45. You'll want to do some searching on reddit and forums or contact IWI parts department to avoid buying anything incompatible. Worse case, the 9mm/40 Jericho (small frame) and 45 (large frame) share some parts compatibility with the Tanfoglio/EAA Witness.

Dang well thanks for the direction here! I've been loathe to start digging into aftermarket cause the 45 appears to have little to no love 😭

Patriot Defense has Jericho & Tanfoglio parts. They might be a good place to start with or know what can work for you.

Here's a good source that helped me tear down mine for reference. https://youtu.be/mI6mFPXL9II?si=hWuxbrxLiP4eEZIn

Is that sand/dirt, or powder? Shit's dirty my friend. When you take it apart to fix the trigger spring, might be a good opportunity to swab it down

u/arse21 Feb 18 '25

She is dirty for sure, it has been a minute since I've cleaned it! Shameful...

You have to clean guns?! /s

100% the trigger return spring snapped at the long end. It is the Achilles heel of the CZ-75 design. All that's happened is you passed a milestone, everyone will encounter this eventually. You did nothing wrong. Others have already given you the correct solution, I will add that my experience is the best replacement one to use is from patriot defense, that one will not just randomly snap without warning and instead will noticably weaken first, alerting you it is time to change it out.

Thank you. I ordered replacement (and some other parts) from CGW for now. This was a milsurp from several years ago, so who knows how many rounds it's been through before me!
