One thing that realy hasn't been covered is if you lighten the trigger weight to much. We have had many rifles the owner has completely backed off the trigger spring pressure so if the rifle is verticle gravity holds the trigger down and they discharge. Hold them horizontally and the triggers seem to function. There is excessive sear engagement and it isn't an issue.
So dont lighten trigger weights to far either the trigger return spring might not be able to hold the trigger back against the sear.
