For some reason, they always seem to re-set the trigger when swapping out a barrel. I've not gotten any more barrels, but did have the trigger job done to mine. It is now 3.5 pounds...which is better than the metric ton that it was out of the box.
I had a buddy tell me that you had to specify IN WRITING that you wanted the trigger left alone when getting a new barrel.
wow man, i wish i new that before i sent them my gun. they really pi**ed me off. i flat out told them that i would no longer recommed their product to any of my customers (i'm in gun sales).
