I bought a tru-fire bear claw release last year.It had a set screw on the trigger,and I had to completely remove it,because it was too sensitive.From looking at your release on tru-fires website,it says the dial adjusts trigger pressure only,and you still have a set screw on the trigger.Back that set screw out on the trigger,or remove it completely,then adjust the dial to get your trigger pressure set right.This quote is from their site...here go check it out,and see if that fixes it.Hope I helped.
