The accu trigger was primarily designed so that anyone could adjust the trigger themselve from 1 1/2 pounds to 6 pounds. It was also made so that it is pretty much impossible for the gun to discharge with out actually pulling the trigger. In order for the gun to fire you have to actually pull the little trigger within a trigger to disengage the sear. This must upset the attorneys cause they won' t have as many cases to try against the gun manufacturers
