Triggertech diamond issue

It seems like your sear might be too tall and dragging on the firing pin, or the firing pin's mating surface could be too tall causing the same thing. The sear releasing would be the click, followed by a delayed firing pin drop.
What action are you using, and if you have live-fired the gun were you getting light primer strikes?

Clean it out.
Lighter fluid or brake cleaner or rubbing alcohol I’ve used all 3
then spray it out with compressed air
I had the same problem

Exact same issue, here is my post from another forum...
Action shot 180 rounds before this appeared, today it worked well for the first 10 rounds I got the gun out of the case, then I let it sit for 30 mins in the cold before firing again, issue had started right at that moment.
The delay is also clearly felt and seen during dry firing (primer issue out of the question now).
Completely stripped the bolt/firing pin setup, reassembled in warm shop, still does it. Everything has been inside for 2 hours now too, cold is not an issue for sure now (although cold may have caused it).
I have 2 Bighorn Origins each sporting their own TT diamonds, we'll call them #1 and #2 (#2 is the one with the issues), and did the following testing...
#1 action and trigger functions fine with both bolts
#2 action and trigger do not function well with both bolts
#1 action does not function well with #2's trigger, with both bolts
#2 action functions well with #1's trigger, with both bolts

I called them up and they’re going to send me two new triggers
Glad to hear they took care of you, but for anyone else reading...
THIS. I had the same issue and this resolved it.

It looks like an issue with the sear height. It's seen most commonly with Bighorn/Zermatt actions and Timney triggers (not knocking either of those products It's just well documented they often don't function well together without some modification). Interested to see if the new triggers cure the problem. If it doesn't you will likely need your cocking piece modified or may need to install a trigger with different sear heights available like a Bix'n Andy Tacsport.
The strangest thing is one gun has thousands of 22 rounds through it and it just started to act up and the other has 100 rounds.
Had the same issue with their two stage diamonds. I bought THREE triggers and they were all messed up on three different actions. TL3, Zeus, and Shadow 40. Said they have to change something in their manufacturing process. They should have a fix for the two stages but I’ve since deployed so I’ll get the triggers when I return.
It’s not giving me the option to post a video when I click attach files for some reason.

Curious though, has anyone else had the issue reoccur after the cleaning ritual? Mine has been fine since but that's only been 60 rds.
This occurred on mine (installed new) after @ 100 rounds (and mucho dry fire practice).
Impact 737R - 6.5CM
I'm betting this is the issue.
Had the same issues as the OP with a Calvin Elite on my TL3. Was fine for a 100rds or so it seemed and then started to get weird heavy, inconsistent pulls.
Swapped to a TT and its perfect.
FWIW, you can send your stuff back to Zermatt and they will fix it for you for free to make it work.
this is how I noticed it on all three of my actions. It would get vastly heavy. In excess of 6lbs which the triggers aren't even rated that high. But this would only happen with my two stage diamonds. My special trigger and single stage diamond were fine. They were older production models from like 3 years ago or something like that.
I just picked up two of the TT 2-Stage Diamonds for my Zeus and my Vudoo. Have people reported the problems with the TT 2-Stage Diamonds? I wonder if the Gold Special Edition Diamonds will also exhibit the issue..
Glad I found this thread. I have the same issue on my diamond straight trigger (single stage). Guess I’ll be calling TT tomorrow
I'm shopping for an R700 clone trigger and the Diamond was at the top of my list.
What available trigger has the best combination of feel, reliability, and user friendliness?

Single stage? https://www.huberconcepts.com/products/single-stage-remington-700-trigger-traditional I'm a huge Huber fan. Reliable, great feel. It doesn't allow you to customize it, but doesn't bother me. Choose the weight you want and be done with it. Also means no random set screws getting loose and your trigger pull changing over time etc..
My gold diamond has no problems whatsoever at ~300rd.
FWIW, neither does the single stage diamond I’ve been running since August 2019, at ~1000rd.
