Some flavor of 2 or 3 dot night sights with no paint on the rear vial(s). I mostly have Ameriglo Spartan Tacticals (their trijicon HD style sight), have pro operators on a one gun, a 2 dot mixed setup on my G35 (Heinie rear w/ 1 vial night sight, Dawson Precision white outline tritium FS) and i think ameriglo pro operators on my 3rd gen 19. FO on my game pistol.
