Very bright sight, but.... - Laser Ammo TAS Pistol Sight - Glock Single Dot Fiber Optic Day Sight

This fiber optic sight is very unique compared to all the other standard fiber optic sight systems. It is an all-in-one sight so the front sight is not needed! Installation is very simple with the screws provided. It is very bright when shooting outdoors or indoors with good lighting. However, the fiber optic is pretty dim in low light settings as to be expected. I have it mounted on a Glock 19 with a viridian pistol light. The sight is slightly visible in a dark room with the viridian pistol light on. I would recommend this sight for outdoor range/ competition style shooting, but I wouldn't recommend this for self defense type scenarios because of the possibility of shooting in low light settings.
