Another way to tweak a trigger that is fairly easy to try before sending it off for work is to take some powdered molly or graphite, use a toothpick or the like and put a little onto the mating surfaces within the trigger mechanism. I did that to my Magbolt and it cut the precieved trigger weight almost in half. I wish I had a trigger scale so I could verify the actual pull weight of it after lubing it. I did that over 2 years ago and it still has a nice feel to it and surprizes me when it goes off. I used the toothpick to rub the dry lube into the mating surfaces real well. I think this helps it self polish those contact points and smooths them out. It sure helped several of my rifles.
