Unfortunately happened to me last weekWell, I just got back from the range this morning and my TT special took a shit the same way, around 550 shots in. Trigger is in a rifle I purchased from Alamo Precision, Defiance anti action in 6.5 creedmoor. Found this thread looking for probable causes... sucks...
