All it takes is removing and replacing the trigger once, without pulling the trigger while installing the screws, to break a Gen 1 sear.... If, instead of breaking in half, the Gen 2 sear knocks the corner off where it rests on the drop mechanism, that could explain all the failures that have occurred IF the trigger was removed and reinstalled, and the person doing it didn't know to pull the trigger before tightening the screws.... I'm not saying it's a great design, to have something that when installed using the wrong method fails.... but unless you find a Gen 2 sear that has deteriorated to the point of being unsafe that has NEVER been removed from the gun, this may not be Crosman's fault.... other than providing a warning about how to properly remove and install the trigger, and what can happen if you don't follow the correct procedure.... My guess is that they don't want to do that, because they don't want anyone tinkering.... Bob
