just id a very simple mod on my mark ii with accu trigger.i dont have a trigger pull gauge to test it but what i got it is very very light pull.all i did was take the spring out and put in a lighter one.how i did that was take out the trigger pin and remove the trigger.take out the sprint and put a #6-32 x 12" machine screw and nut in the hole and find a spring the same diameter as the stock spring but lighter.then put everthing back together.
