Swapping out those factory plastic Glock sights is one of the easiest upgrades you can make, and this Night Fision set gives you a real reason to do it. The GLK001003OGW pairs a green tritium front dot wrapped in a high-visibility orange ring with a green tritium rear framed by a white outline. That color separation means your eye jumps straight to the front sight in daylight, then you get three glowing dots when the lights go down. It fits a huge chunk of the Glock lineup, including the 17, 17L, 19, 22 through 28, 31 through 35, and 37 through 39.
What sets Night Fision apart from the usual night sight is how the vials are held. Instead of aluminum sleeves and painted-on rings that fade or chip, they use a patented injection-molded polymer sleeve that locks the tritium in place and forms the colored ring they call the Perfect Dot. A domed lens sits over each vial to collimate the tritium glow into a crisper, tighter dot rather than a soft blob. The result is a sight picture that holds up in the dark without losing that daytime clarity.
The sight bodies are CNC machined from quality steel and finished in Black Nitride, which fights corrosion and keeps them looking sharp after countless draws from the holster. The company knows tritium too, having spent years producing the tritium-filled lensatic compass for the US military, so the glow is engineered to last.
The front post on a Glock is a straightforward job, but the rear sight rides in a tight dovetail and can put up a fight. Night Fision recommends a gunsmith or the right sight-pusher tool, and plenty of folks knock the install out in minutes once they have the proper gear. Take your time, confirm your zero at the range, and you will have a set of sights that outlasts the gun they are riding on.
This set is designed for a wide range of Glock pistols, covering the 17, 17L, 19, 22 through 28, 31 through 35, and 37 through 39. It uses the standard Glock front post and rear dovetail mounting. Double-check your specific model and generation before installing to make sure the fit is right.
The front post is a quick job, but the rear sight rides in a tight dovetail that can take some muscle and the right tool. Night Fision recommends a gunsmith or a proper sight pusher rather than punching it with a hammer. Many people get the job done in a few minutes once they have the correct tools on hand.
Instead of aluminum sleeves with painted-on rings that can chip or fade, Night Fision uses a patented injection-molded polymer sleeve that locks the tritium vial in place and forms the colored ring. A domed lens over each vial focuses the tritium glow into a sharper, tighter dot. That gives you a cleaner sight picture in the dark and better daytime contrast.
Tritium night sights typically stay usefully bright for well over a decade, gradually dimming over time as the isotope decays. Night Fision has decades of experience encapsulating tritium, dating back to military compasses, so the vials are built to hold up. You will get years of reliable low-light performance out of this set.
