Trigger: It feels stiff or sticky, what do I do?

The trigger should flop back and forth freely with gravity. Check for wood rubbing against the side of the trigger. If there is contact, relieve a small amount of wood. Polish the trigger pin by spinning it in a drill with fine sandpaper. Also ensure there is at least a small amount of take-up (play) at full-cock, this lets the sear seat fully in the notch.
