Night Fision GLK001014YGZ Tritium Night Sights for Glock - Black | Green Tritium Yellow Ring Front Sight, Black Rear Sight

Night Fision's GLK001014YGZ tritium night sights for Glock bring reliable low-light performance to one of the most popular handgun platforms. These sights combine glowing tritium vials with a bright yellow ring on the front sight, giving you fast target acquisition whether you're shooting in daylight or complete darkness. The rear sight is black, keeping your focus where it matters most. If your Glock lives in a duty holster, nightstand, or goes on weekend range trips, a quality night sight upgrade is one of the smartest moves you can make.

Night Fision engineered these with a patent-pending injection-molded sleeve that holds the tritium vial securely while amplifying its glow—a design that sets them apart from standard tritium offerings. The sights are CNC machined from 4140 steel and finished with black nitride coating, built to handle years of holster wear and environmental exposure without fading or corroding. Construction is USA-based using Swiss tritium, so you're getting proven components backed by solid manufacturing.

Installation should be handled by a qualified gunsmith to ensure proper fit and function on your Glock. Once mounted, these sights work without batteries, ambient light adjustment, or electronics—they glow for years on their own. Daytime shooting is equally competent thanks to the fluorescent yellow ring providing a bright sight picture in sunlight.

Do I need a gunsmith to install these night sights?

Yes, professional installation by a qualified gunsmith is recommended to ensure proper fit, function, and safety. Glock sights require specific tools and knowledge to avoid damage to your firearm.

How long do the tritium vials stay glowing?

Tritium self-illuminates without batteries or charging. Swiss tritium vials like those in the GLK001014YGZ maintain useful brightness for many years; the exact duration depends on conditions and ambient light exposure.

Will these sights work well in daylight?

Absolutely. The yellow fluorescent ring on the front sight is bright in daylight and creates a sharp sight picture in sunlight and at the range. The tritium becomes the primary asset in low light; the fluorescent ring carries the load when the sun is up.
