XS Sights Offers R3D 2.0 Tritium Night Sights for Glock and S&W

Building on the popularity of the original R3D night sights (below), XS Sights offers the improved second gen with the 2.0. Promising significant improvements over the original, the R3D 2.0 offers bigger and brighter rear tritium dots. Additionally, available in standard and suppressor height, the updated sights feature an improved and easier installation process.

Featuring a black nitride finish, the updated R3D 2.0 sights double the corrosion resistance of the original black oxide treatment. As a result, the new sights promise a longer, more durable lifespan. Likewise, the nitride finish works with the serrations on the rear sight to reduce glare and enhance the sight picture.

A huge upgrade from the original R3D is the two rear tritium dots, which are now bigger and brighter. Correspondingly, the rear sight lamps are surrounded by PVC rings for a more defined edge. As a result, this helps further to differentiate the front dot from the rear lamps.

Wider than many on the market, the 0.145-inch front sight features a high-contrast orange or green dual-illuminated photoluminescent Glow Dot with a tritium vial. The Glow Dot activates after absorbing ambient light in low-light conditions. Likewise, the self-luminous tritium lamp can glow in low or no light for up to 12 years.

Installation is easy and requires no filing or hammering via the new EasyPress features. Built into the dovetail of the R3D 2.0, the EasyPress features pair a crush zone with a lead-in edge. As a result, this reduces the force required for installation by up to 50%, according to the company.

The directional lead allows the sight to be pressed over 1/3 of the way through the slide’s dovetail before making full contact. Once this contact is made, the crush zone starts collapsing, assisting with easy final installation. The new XS R3D Night Sights are available for all Glock and select Smith & Wesson pistols.

The XS R3D 2.0 Night Sights are available for the following models:


  • All models – Standard height and suppressor height 


  • M&P/M&P 2.0 Standard Models (Novak style rear sight) – Standard height
  • M&P/M&P2.0 C.O.R.E. (optics ready) – Standard height and suppressor height

On November 9, 2020, Personal Defense World reported:

Glock pistol owners get new accessories to choose from with the announcement of XS R3D Night Sights in suppressor heights. The new offering comes as XS re-launches the former RAM Night Sights as R3D. The name change stems from a trademark issue.

“We always like to be smart with our resources and lengthy litigation wasn’t the way to go,” said Zack Kinsley, Marketing Manager for XS Sights. “To our support channel, please know it will not affect our forward momentum. We are excited to announce the new suppressor height line extensions for popular LE and aftermarket pistols, and we plan to continue with the R3D product line full speed ahead.”

XS R3D Night Sights come in suppressor heights to fit Glock pistols.

The new R3D sights feature radioactive material in a traditional three-dot tritium notch and post sight picture. The rear sight features a blacked-out style, increasing contrast. Meanwhile, the front sight comes in bight orange or green.

XS’s proprietary Ember Glow Dot technology allows the front sight to absorb ambient light. Additionally, the material glows in low light. The front tritium lamp also charges the Ember Glow Dot. The system makes the front sight glow brighter than the rear, keeping focus downrange.


  • The brightly colored Ember Glow Dot in the front sight is a much brighter color which differentiates the front dot from the two rear dots.
  • The notch is 15-percent wider than the front sight, allowing more visible light around the front sight.  This makes it easier to see the front sight in changing light conditions and when shooting on the move, aiding in sight alignment, and increasing accuracy.

The R3D Nights Sights get CNC machined from bar stock steel. A rust-preventative coating makes them durable and reliable, according to XS Sights. The sights fit standard holster options. For more information, visit xssights.com.
