Resurrecting this as I have some more info now.
I have two TrigegrTech triggers purchased directly from Triggertech, a special 2 stage and a diamond 2 stage. The special started losing it’s weight setting after a couple hundred rounds of fire, requiring me to re-set the weight on one of the stages (forget which one) or else it’d hang fire or other weird stuff. Once it was set, it was back to 100% until it loosened up again.
I purchased a diamond to use as my primary trigger and keep the special as a backup. Approximately 350 rounds into firing the diamond, if started hang firing no matter what I did until I flushed it with lighter fluid, then it was seemingly back to 100%. I chocked it up to debris/lube getting in it and went about my business.
But, then the same thing kept happening, except with increasing frequency. It went 200 rounds, needed a flush, went 100 rounds, needed another flush, until last time I took it to the range it was hang firing after just 60 rounds. Now, even after a thorough flush followed by compressed air, it’s still hang firing no matter what. I had minimized any lubricant use to the point where I stopped except for a dry film (hornady one shot), yet it still progressively got worse. To be clear, my action was never dripping wet with liquid lubricant, and was kept relatively clean either kept covered at matches or shot on a bench at the range.
I finally emailed triggertech to get it sorted out and have received a less than stellar response. They’re insinuating that it’s most likely I’ve been contaminating it with debris and that I can send it in (at their expense, to be transparent) for them to inspect and they’ll send me out a new one. I said that wasn’t going to work because I need a trigger working now as I’m traveling for a match next week and it just shit the bed this week. Instead they’re doubling down saying that it’s most likely due to debris or abuse and that until they can confirm I’ve shipped them it, they won’t dispatch a replacement.
Anyways, given the importance of reliability of a trigger, first and foremost for safety, and second for real world use, I am not going to be using their products moving forward. It’s unacceptable I need more than two of their products for one rifle to ensure I always have a reliable trigger to use. Once I get replacements, they’ll be getting sold off.
