Night Fision Tritium Night Sights for Glock - Yellow Front/Black Rear Rings, Green Tritium

Night Fision tritium night sights for Glock deliver reliable low-light aiming when it matters most. This set pairs a yellow front sight ring with black rear rings and green tritium vials, giving you a high-contrast sight picture that works in darkness, dim indoor ranges, and dawn/dusk hunting conditions. Night Fision loads more tritium into each vial than most competitors, so you get a brighter glow that persists longer without external light. The domed lens is engineered to collimate the tritium's light output, creating a sharp, defined sight picture instead of a hazy glow.

Built from CNC-machined steel and finished with black nitride coating, these sights are tough enough for duty, sport, and field use. The patented injection-molded sleeve design locks the tritium vials in place using ballistic materials, so recoil and impact won't shift your zero. Made in the USA with Swiss tritium—a mark of quality in the night sight world—these sights represent the kind of no-nonsense upgrade that serious Glock shooters and hunters rely on for reliable sight acquisition in low light.

Installation by a qualified gunsmith is recommended to ensure proper fit and zero. Once installed, you'll have a set of night sights that work passively (no batteries, no buttons) and require zero maintenance. Whether you're running a nighttime self-defense drill, hunting in early morning, or simply want the safety of reliable sight picture in any light condition, Night Fision tritium sights earn their place on a carry or duty gun.

Frequently Asked Questions

What Glock models do these night sights fit?

These Night Fision tritium sights are designed to fit Glock 42, 43, 43X, and compatible models. A gunsmith can confirm fitment on your specific gun and install them properly.

How bright are these night sights compared to factory Glock sights?

Night Fision sights contain more tritium than standard aftermarket night sights, and the domed lens design is engineered to collimate and sharpen the glow. This results in a brighter, crisper sight picture in low light—though the actual brightness depends on the age of the tritium and ambient light conditions.

Do these sights need batteries or charging?

No. Tritium night sights are completely passive; they generate a faint self-luminous glow at all times and require no batteries, charging, or maintenance. The glow is always available, even if you can't reach a flashlight or headlamp.

What's the difference between yellow front and black rear rings?

The yellow front ring creates high contrast against the black rear rings, making it easier to acquire a fast, clear sight picture. The bright front sight naturally draws your eye, while the black rear rings frame it for alignment. This is a proven carry and combat sight configuration.
