WA, I think it is mostly that people are expecting the performance of a $200 trigger out of a factory stock trigger that seems to be at best a marginal design in the first place. As far as the problems I am having with mine go, if I follow the method that I posted earlier, there isn't enough overtravel to get it to the point that the trigger will even break; I have to back out the overtravel at least another turn to get a reliable break. Not going the way it is supposed to leaves me with serious doubts in my mind, and because of that, I put in a little more of a safety margin by increasing engagement a little and adding a little more pull weight. Hopefully I will just be able to get a new trigger soon and just be able to forget about it. Although, since it is 30+ years old and belonged to a family member that is no longer here, I kind of feel bad about wanting to do that, or even messing with it period, but the screws weren't sealed and were starting to shift a little. I think it would be more of a shame to not use it though. Sorry, a little OT.
As a side note, the only safeties that I would trust to do a safety's job are the ones that block the striker, like the winchesters. If I were doing anything other than punching paper, I would have the bolt shroud replaced with one that has such a safety.
