XS Sight Systems R3D Night Sights for Glock 20/21/29/30/30S/37/40/41 - 3-Dot Orange Tritium

The XS Sight Systems R3D night sights are a 3-dot tritium sight set purpose-built for Glock 20, 21, 29, 30, 30S, 37, 40, and 41 pistols. The front sight features a green tritium lamp encircled by a high-visibility orange ring, paired with two orange tritium rear dots. That high-contrast front halo pulls the shooter's eye to the front sight faster than an all-green configuration, helping you drive the gun on target during high-stress home defense or concealed carry.

The rear sight is precision CNC machined steel with a snag-resistant black finish and a rear sight height of 0.340", giving you a standard co-witness on the supported Glock models. Anti-glare serrations on the rear sight face knock down daytime reflection, while the self-illuminating tritium vials keep your sight picture crisp in low light or total darkness with no batteries required.

Complete with anti-glare technology, superior contrast, and a familiar 3-dot design, this set builds on a proven XS Sight Systems layout for fast sight acquisition across the supported Glock pistols. Whether you run a Glock 20, 21, 29, 30, 30S, 37, 40, or 41, the R3D delivers an intuitive sight picture around the clock.

Your purchase includes one XS Sight Systems R3D 3-Dot front and rear night sight set for Glock 20 / 21 / 29 / 30 / 30S / 37 / 40 / 41.
