If there is a 1/16" allen screw that extends down inside the trigger guard on the trigger, then it is the 2009 trigger. If there isn't a screw there, then it is an X-Mark pro. Either way, you can adjust them according to my earlier
No you cannot. I can unsrew the weight adjustment screw counterclockwise until the screw falls out and it still pulls 3 1/2 lbs.
