I have a brand new G19 I purchased about 2 months ago. It came with Glock night sights. I took it out today and the rear sight, both dots, appear orange in color when in light. When taken into the dark they still glow green. The front sight, in daylight, still appears as a white dot. Anyone know what happened? I also have a G27 with night sights and the all dots are still white when in light.
