The XS Sights R3D suppressor height night sight set for Glock 43X/48 puts reliable iron sights on your carry gun when it matters most — in low light or no light. Built on the proven 3-dot tritium design, these steel sights add XS's proprietary Glow Dot technology to the front sight, which absorbs ambient light during the day and delivers a visible glow when darkness falls. That dual-source brightness makes the front sight the natural focal point, letting your eye index faster and lock on target with confidence.
The real advantage of the R3D platform is the balance it strikes between brightness and usability. Tritium vials in the rear sight are intentionally dimmer—2-dot configuration with an anti-reflective lens—so they guide your sight picture without competing with the front sight for your attention. The brighter front tritium vial actually charges the photoluminescent Glow Dot slightly, boosting that signature glow and keeping your sight picture crisp and intuitive. That's the R3D philosophy: better ergonomics through clever optics design, not just brute brightness.
These are suppressor-height sights, meaning they sit tall enough to co-witness with RMR, SRO, and Holosun 507c optics mounted on MOS-pattern slides. Whether you're running a reflex sight or trusting iron backup, the height works. The sights are machined steel, tough enough for serious use, and engineered for standard holster compatibility. A rear sight ledge means you can manipulate the slide one-handed if needed, and the serrated rear helps reduce glare downrange.
| Sight Type | 3-dot tritium night sights with photoluminescent Glow Dot |
| Front Sight | Tritium with orange Glow Dot |
| Rear Sight | Tritium 2-dot with anti-reflective lens |
| Height Style | Suppressor height (co-witnesses with RMR, SRO, Holosun 507c) |
| Material | Steel, CNC machined |
| Compatible Platforms | Glock 43X, Glock 48 |
| Optic Co-Witness | Trijicon RMR, SRO, Holosun 507c series, Vortex Viper on MOS slide |
Yes. These R3D sights are suppressor height, designed to co-witness with Trijicon RMR, SRO, Holosun 507c series, and Vortex Viper optics on MOS-pattern slides. They sit tall enough that your irons remain visible and functional if your red dot fails.
No. The Glow Dot is photoluminescent, meaning it charges from any ambient light during the day—sunlight, streetlights, even interior lighting. It glows in darkness without any external power or activation. The tritium vials provide a separate light source and work independently at night.
Yes, they fit standard holster options for the Glock 43X and 48.
The front sight has a brighter tritium vial paired with the photoluminescent Glow Dot to create a prominent aiming point. The rear sight uses a dimmer 2-dot tritium configuration with an anti-reflective lens, so it guides your alignment without pulling your focus away from the front sight. This design speeds up target acquisition in any light.
