This is an exploratory thread to try and understand the scope of an issue we've been having with TT triggers. Is it an isolated issue, or is it more widespread?
First off, I'll say I love me some Trigger Tech triggers. I love the ease of install/timing, and I love how they feel when they are working correctly. All of the TT triggers we get come from TS Customs, and many of them are pre-installed in the rifles or barreled actions.
Early this spring, on a live stream with our first RimX 22lr action... we had a TT diamond go down. It was working fine... and then started hang firing. Upon pressing the trigger, I'd feel/hear a tiny tick, but the sear would not fall and the cocking piece/firing pin would not move. Then by just touching the bolt handle, bolt shroud, or wiggling the trigger shoe... it would fire. I replaced the trigger with a different TT diamond... and the problem disappeared, and has not returned in over 10,000 rounds.
A few months later we sent a RimX with a TT Diamond single stage to a customer in Tennessee, and within 200 rounds, he too started having the exact same issue. He contacted triggertech, and they sent him a new trigger and it has been working fine since.
Another few months later, I was working with another TT Diamond single stage on a RimX 22lr... and it too began having the exact same hang-fire problems the previous failures exhibited. I replaced it with a different TT Diamond, and again... the problems disappeared.
A month or so ago, I began testing on the new 17WSM RimX and had a TT Diamond single stage on there. ...and again began having hang fires within 200 rounds. I replaced the trigger with a TT Diamond two-stage, and have fired over 1000 trouble-free rounds since. What's interesting here, is that many have thought that ignition issues such as those reported here are due to the Zermatt actions, namely the RimX, having only 170 thousandths of pin fall. (if memory serves) Well, the new 17WSM action has 250 thousandths of pin fall, and it also has a very heavy firing pin spring. This configuration is not prone to ignition problems, historically. I took a different diamond single stage that was having issues in a RimX 22lr, and installed it in the 17WSM... still same issue. Put the 2 stage that was functioning back in... and the problems vanished.
Today, I was notified by a customer that just received his brand new TS Customs RimX 22lr that his TT Diamond single stage is doing the exact same thing as described above. I fired 250 rounds through this rifle before sending it out, and it never had a single problem. Flawless. His first range trip, he fires 30 trouble free rounds, and then it starts hang firing just as described above. He's being sent a new trigger, but this is clearly becoming a serious problem.
Subsequently I've been on the phone with Zermatt and TS Customs, and have heard about many more instances of similar behavior from TT triggers in several other actions. Impact as well as Lone Peak. One guy went through 3 TT diamonds in a Lone Peak, and finally had to go to a different trigger manufacturer. Lone Peak sent a complete new bolt with complete fire control assembly, and that had no change on the issue. I've heard of the issue happening with RimX, Origin, TL3, Impact, and Lone Peak actions. I heard a report of one shooter going through 5 TT triggers, and only 2 of them did not exhibit the issue described above in his rifle. This would seem to rule out some specific design element in the actions as a cause. Especially considering a simple trigger replacement always seems to remedy the issue.
The recurring theme is that it doesn't happen right away. It takes 100-300 cycles, live or dry fire, before the issue starts showing up. Once it shows up, the behavior seems always the same. Hang fires, in which the rifle will not fire upon the initial press, but wiggling the trigger shoe or bolt will cause the sear to drop and the pin to fall.
I have not heard of a TT trigger having this problem prior to this year. However, in the last 9-10 months... this has been a recurring thing I've had to deal with personally and have heard about multiple times from multiple sources when I would inquire about the issues.
I'm basically at wits end here. I love the ease of installation/timing on the TT's. I love how they feel. I love the ease of pull weight adjustment. They are just really easy to get along with... when they work. Other triggers can be made to work in our rifles, but it requires a ton more effort to get them timed right, adjusted properly, and it's difficult to have confidence they will STAY adjusted even after we've done all that. The beauty of the TT's has always been the ability to just stick them in there and they work perfect right out of the box. However, this past year has been a nightmare. Based on conversations I've had over the last year, it doesn't seem to be an isolated problem or problems with just one type of action. ...though I would like to know if that's the case.
Have you had similar problems with a TT? If so, could you report what action the TT was attached to, and which model of TT trigger it was? Were you able to resolve the problem without replacing the trigger? If so, what did you do?
