Why is it so aggravating to set the darn things? Is there some kind of design flaw. Most of the time I can only get the trigger to catch in the night latch notch, no way do I get the pan further up on the trigger so I can move to the night latch when I am ready.

Do yours have the newer stainless rod style dogs? Also do they have the pressed in bump in the pan where the dog engages? Last year rob caven changed the pan and the newer ones are easier to set. What happens is the thicker dog causes the power jaw to be pushed down further and the jaw hits the pan connecting arms where they go through the spring pin. You can buy new pans and pins. Very easy to change out. Or you can bend that part of the pan up a hair and that usually fixes it.
