XS Sights' DXT Big Dot Night Sights for Glock are an excellent choice for those who want to enhance their EDC pistol's performance. Designed for defensive use, the DXT Night Sights feature a reflective white dot that bounces ambient light to provide increased low light visibility alongside the glowing tritium center. The front sight is large and highly visible, which helps solve many issues from aging eyes to deteriorating vision.

The high-contrast white front sight is complemented by the low-profile V rear, which provides greater visibility of the front sight. The simple dot-the-"i" sight picture prevents confusion between the front and rear sight in high-stress situations. The rear sight has a white outline with a tritium center, and the rear sight ledge is designed for one-handed slide manipulations.

XS Sights' founders engineered the DXT Night Sights based on the express sight concept, which is designed to give you a visible and combat accurate flash sight picture when seconds count. They are big, bright, and easy to see day or night.

DXT Big Dot Sights Features:

  • Tritium powered front sight with high-contrast white dot
  • Big Dot front measures 0.188"
  • Low-profile V rear provides greater visibility of front sight
  • Simple dot-the-"i" sight picture
  • Rear sight white outline with tritium center
  • Rear sight ledge for one-handed slide manipulations
  • Durable CNC machined steel 
  • 12 year warranty on tritium
  • 30 Day Satisfaction Guarantee
  • Fits standard holster options

    Great sites - Repeat customer

    Posted by BartLanz on Dec 1st 2022

    I purchased the standard version of these in 2018 after the recommendation made by James Yeager. I have been shooting them and using them for 4 years now and have no regrets, the sites are great, allow for easy and fast acquisition in all lighting scenarios. I am now outfitting a G19 with a red dot, and after looking at other sites, I have decided to "come home" to that which has worked well for me and got the suppressor height sites for this one.

    Big dot Suppressor height sights

    My second set of XS sights I got. This set I had to do a little more filing than I thought I would have to do. Other than that it was an easy install again. Love how they co-witness my slide red dot. They are so much easier to pick up than factory Glock sites. Should have got these years ago!!
