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

The XS Sight Systems R3D 2.0 night sights deliver a brighter, more durable aiming solution for Glock 42, 43, 43X, and 48 pistols. The front blade is built around a large orange photoluminescent ring surrounding a tritium lamp, drawing the eye forward for faster sight acquisition in daylight and low-light conditions alike, while the rear sight pairs a tritium lamp with a wide notch that supports a clear, uncluttered view of the front post.

This set is machined from steel and cut to suppressor/optic height, so the iron sights clear a mounted red dot and provide a clean co-witness or lower-third co-witness with most slide-mounted optics on Glock 43X and Glock 48 slides. The 3-dot configuration uses orange tritium lamps front and rear for self-illuminated aiming without batteries or ambient light, giving you 24-hour visibility across the carry, duty, or home-defense handgun.

XS engineered the R3D 2.0 series to install with roughly half the force of comparable night-sight sets, making push-and-seat fitting easier on the dovetailed Glock front and rear sight channels. Whether you run a slimline Glock 43X or 48 with an optic, or simply want a high-visibility suppressor-height set for a Glock 42 or 43, these sights give you a reliable, snag-resistant aiming reference.
