Had a Trigger Tech Special stop resetting trigger after 20 shots. The folks who built the rifle said they had seen that issue with the Trigger Tech Special several times. Contacted TT and they were less than helpful on resolving an issue with the new trigger. Bought a Timney and moved on. Do have a TT Primary that is working still. Probably just my bad luck, but I will say that TT was not high on after the sale customer service on that particular day. Just saying none of them are probably perfect. I could see trying a Diamond out on an appropriate rifle.
