I just purchased a SIG P226 DAK with what should be a 6.5 Lbs trigger, but it feels a bit heavier. I know that SIG will not adjust the weight on the trigger below 6.5 Lbs. Can it be dropped to say 4.5 Lbs safely? Triggers on Glocks can be dropped to 3.5 Lbs and come standard at 5.5 Lbs. Wondering what my options are.
