XS Sight Systems R3D 2.0 Night Sights for Glock 43X/48 - Suppressor/Optic Height - Green Tritium

The XS Sight Systems R3D 2.0 suppressor-height night sight set brings a fast, intuitive sight picture to Glock 42, 43, 43X, and 48 pistols. Designed for everyday carry and defensive use, the R3D 2.0 builds on XS's proven R3D platform with a brighter, more robust construction and a tall sight profile that allows co-witness with slide-mounted red dot optics and clearance for threaded barrels and sound suppressors.

Both the front and rear sights carry self-illuminating green tritium lamps for dependable visibility in low-light and no-light conditions. The front blade combines the tritium lamp with a photoluminescent ring that charges from ambient light to provide an additional high-contrast aiming reference during the day, while the rear sight features two tritium dots flanking a plain notch so the shooter's eye locks onto the front sight. The result is a clean 3-dot night sight picture that draws focus quickly under stress.

The sights are precision machined from steel with a corrosion-resistant black nitride surface finish, and they install in the factory dovetail cuts on compatible Glock slides. This set is rated for DIY installation, and the suppressor / optic height front blade (approximately 0.275" tall) provides the necessary clearance for most popular pistol red dot footprints.
