Night Fision Standard Height Tritium Night Sight Set for Glock 17/19/34 - U-Notch Rear, Black Ring, Steel Nitride

The Night Fision Standard Height Tritium Night Sight Set brings reliable low-light shooting to your Glock 17, 19, or 34 with a U-notch rear and black ring front configuration. Built from machined steel with black nitride coating, these sights are engineered to cut through darkness and poor lighting without batteries or bulky electronics. Whether you're training at night, carrying for self-defense, or hunting in twilight conditions, tritium night sights give you a glowing sight picture when your flashlight isn't an option.

Night Fision loads more tritium into each vial than most competitors, paired with a domed lens that collimates the light for a sharper, more defined glow. The injection-molded sleeve design locks the tritium vials securely in place using ballistic-grade materials, so your sights stay put through thousands of rounds and hard use. The black nitride finish resists corrosion and wear—important when you're relying on these sights in field conditions.

Installation is straightforward but gunsmith installation is recommended to ensure proper fit and function on your specific Glock model. These sights are built in the USA with Swiss tritium, combining domestic manufacturing with proven European tritium quality. Night Fision's design philosophy prioritizes durability and visibility when it matters most: when your target is in shadow and your seconds count.

Frequently Asked Questions

Will these night sights fit my Glock?

This set is designed for Glock 17, 19, and 34. Night Fision also makes this sight pattern compatible with Glock 17L, 22, 23, 24, 25, 26, 27, 28, 31, 32, 33, 35, 37, 38, 39, and 45—check your specific model before ordering. If you're unsure, a gunsmith can confirm fitment.

How bright are tritium night sights, and how long do they last?

Night Fision sights contain more tritium than average night sights, producing a defined glow in darkness without needing a light source or battery. Tritium has a half-life, so brightness will gradually dim over time, but these sights are built to remain visible for years of normal use and storage.

What does the domed lens do?

The domed lens is engineered to collimate (focus) the tritium light rays into a sharper, more defined sight picture. This improves your ability to aim precisely in low light compared to flat-lens designs.

Should I have a gunsmith install these, or can I do it myself?

Gunsmith installation is recommended. While some experienced shooters handle sight installation themselves, a gunsmith ensures proper fitment, correct windage and elevation, and that your sights are secure before you carry or train with them.
