On a pure tritium level this Night Fision GLK11OGXG Costa Ludas XG Tritium Front and Rear Sight Set is incredibly bright; however the front sight receives a white serrated edge due to the coating process. However the rear sight has a precision cut shape that ensures the rear sight picture is large enough to acquire your target every time. Additionally the rear sight of this Night Fision GLK11OGXG Costa Ludas XG Tritium Sight Set is optimized for sighting in the dark; the rear sight does not have serrations and therefore cannot be carried unless in an area with a great amount of light.
