CGW has a note to call them on how to tweak that spring but I havent seen any of you guys talking about this. I was ordering some spare parts and figured that was a good spring to have but I have yet to tear into my gun that far. Its the one screw I havent messed with yet but I have the stake tool and read about finding the sweet spot in terms of tightness as to not twist the spring out of alignment. I havent read anything about tweaking the spring though. Are you guys tuning the spring in
