The XS Sights R3D 2.0 Pistol Sights Orange for Glock delivers reliable, fast-target acquisition with a proven blend of traditional three-dot accuracy and modern illumination. From the high-contrast tritium front and rear with a bright glow dot to the photoluminescent dot that absorbs ambient light for low-light visibility, these sights ensure quick, intuitive sight alignment across a range of lighting conditions. The wide notch rear features serrations and an anti-reflective lens, reducing glare and helping you maintain focus on the front sight in dynamic shooting scenarios. Built with a corrosion-resistant Black Nitride finish, the R3D 2.0 pair maintains its edge against wear while preserving an understated, durable profile. The traditional three-dot tritium notch-and-post sight picture remains familiar to experienced shooters, complemented by the orange accents for rapid sight acquisition. Compatible with Glock Gen 1 through Gen 5, including MOS models, and proudly manufactured in Fort Worth, Texas, these sights fit Glock 17, 19, 22, 23, 24, 26, 28, 27, 3136, 38, 39, 45, and 47 frames, delivering dependable performance for duty, competition, or personal defense.
