On top of tuning the screws, I also sand/stone and polish the trigger and sear. Plenty info on the net on how to gunsmith triggers. I like the non-accutriggers cause they are nice to work on and when done they are crisper than any aftermarket trigger. Mind you it's not super easy, so if you're not mechanically adept, just adjusting the screws and maybe swapping springs is more than good enough.
