Night Fision GLK003003OGW Tritium Night Sights for Glock - Black | Green Tritium Orange Front, Green Tritium White Rear

Night Fision GLK003003OGW tritium night sights bring reliable low-light capability to your Glock carry gun. Built around self-illuminating tritium vials, these sights cut through darkness without batteries or activation—they're ready the moment you need them. The orange front sight with green tritium and white rear outline deliver fast target acquisition in any lighting condition, from dimly lit indoor ranges to late-evening field work. If you carry a compact or subcompact Glock and want sights that perform when ambient light fails, these are a legitimate upgrade from factory plastic.

Night sights aren't just for tactical operators. Hunters checking game after legal shooting hours, sport shooters running matches in low light, and defensive-minded carriers all benefit from tritium. The contrast between the bright front post and outlined rear gives you a usable sight picture even when you can't see the target clearly. Unlike battery-powered optics, tritium doesn't die in your safe—it glows steady for years, with no charging required.

These sights replace your factory Glock sights completely, so installation requires basic gunsmith tools or a trip to your local shop if you're not comfortable with the work. The green tritium front and rear with orange and white outlines give you excellent sight differentiation and speed in finding your sight picture under stress or in less-than-ideal conditions.
