The Best Night Sights for Glock Firearms

Glock handguns have earned their reputation for being reliable, durable, and high-performing. Now, imagine enhancing your Glock pistol with XS Sights' tritium night sights to combine the best of both worlds.

Typically, Glock pistols come with plastic sights that may not be suitable for everyday carry (EDC) or home defense situations. XS Sights offers a robust alternative to Glock factory sights, with iron sights designed to withstand years of rugged use while remaining securely attached to your firearm.

What sets XS Sights apart is our use of tritium, a self-illuminating material that ensures a clear sight picture even in low light conditions. Unlike traditional sights, tritium glows consistently, eliminating the need for batteries.

Our tritium night sights for Glock are designed to provide high contrast and maximum visibility, even in bright light settings. They are engineered to withstand the rigors of regular use, with a service life of 25,000+ rounds.

XS Sights Tritium Night Sights for Glock

We offer a variety of sight solutions for Glock pistols, depending on which model you own and how you plan to use it. Learn more about some of our sight models below!

DXT2 PRO & DXT2 Night Sights offer the fastest sight acquisition on the market. The big dot front sight and open rear sight allow a greater field of view downrange, increasing front-sight acquisition speed. The simple dot-the-i sight picture reduces sight-alignment time by eliminating an extra focus point compared to traditional notch and post sights and prevents confusing the front and rear sights in high-stress or low-light conditions. DXT2 Sights are available in a Standard Dot (0.140”) or Big Dot (0.188”) front sight. The center of the front sight post has a tritium insert combined with a high contrast photoluminescent ring to provide a visible front sight in bright daylight and into complete darkness.

R3D 2.0 & R3D Night Sights offer an enhanced notch and post sight picture, built for a lifetime of hard use. All XS sight systems are designed around highly visible front sights to enhance front sight focus. R3D sights feature a brighter tritium vial in the front sight to increase front sight focus. The rear features a simple blacked-out face with a wide notch to increase visible light around the front post.

XS front sights are equipped with our proprietary photoluminescent Ember Glow Dot Technology. The Glow Dot features a high-contrast color in bright light, absorbs ambient light, and glows in low light, providing high visibility and fast target acquisition, no matter the lighting conditions. Ember is available in multiple colors to satisfy personal color preferences. DXT2 and R3D sights are available with a tritium or non-tritium rear option to fit your shooting style.

Brief History of Glock

Glock was founded by Gaston Glock in 1963. Some of the earliest products produced by GLOCK GesmbH were curtain rods for the consumer market and knives and entrenching tools for the Austrian military.

When the Austrian military began looking for a new service pistol in the 1980's, Glock assembled a team and began designing and developing a new handgun. The Glock 17 9mm pistol was the result of that effort, and it quickly became the service pistol for the Austrian military.

The Glock 17 proved to be such a successful design that it was soon adopted by militaries and police forces around the world. Today, Glock handguns are some of the most popular on the market, with models like the Glock 19, Glock 26, and Glock 43 becoming household names.
