XS Sight Systems R3D 2.0 Suppressor Height Night Sights for Glock 20/21/29/30/30S/37/41 – Orange Tritium Front, Black Rear

Upgrade your Glock’s low-light performance with the XS Sight Systems R3D 2.0 Suppressor Height Night Sights, purpose-built for Glock models 20, 21, 29, 30, 30S, 37, and 41 — including Gen 1–5 and MOS variants. Engineered and proudly manufactured in Fort Worth, TX, these sights deliver a proven tritium and photoluminescent combination that performs across every lighting condition.

The orange photoluminescent glow dot up front absorbs ambient light and radiates in low-light environments, while tritium inserts in both the front and rear provide reliable visibility in total darkness — no batteries, no charging required. The traditional 3-dot sight picture keeps your target acquisition fast and intuitive, whether you’re at the range or relying on your Glock for personal defense.

The wide notch rear sight features serrations and an anti-reflective lens to eliminate glare and improve sight alignment under pressure. A durable Black Nitride surface finish provides long-lasting corrosion resistance, making these sights tough enough for hard carry and adverse conditions. Suppressor-height clearance ensures full compatibility with suppressor-ready setups and co-witness capability with optics on MOS-configured pistols.
