So I adjusted my X-Mark Pro down to ~2.5 lbs yesterday and I found today that it had crept back up to around 4 lbs. I readjusted the trigger again and I'm going to see if there is any future inconsistency. I searched and found a few threads about this problem with the X-Mark Pros, but none of them said if they tried multiple times or not. I'm hoping that I will be able to get it to stick, but maybe that is just wishful thinking. Anyone else have some experience with this?
