The XS Sights R3D Night Set for Glock 42/43/43X/48 brings trusted low-light performance to compact and subcompact carry guns. This bulk 20-pack offers a practical way to outfit a team or re-equip your personal rotation with sights designed for real-world defensive shooting. XS Sights combines tritium and photoluminescent technology in a three-dot sight picture that works when it counts—whether in dim indoor spaces, dawn/dusk conditions, or complete darkness.

The R3D system uses a tritium-filled front post and rear notch paired with a high-contrast glow dot that absorbs ambient light and glows in low-light situations. The wide notch rear sight and anti-reflective lens reduce glare and unwanted reflections, so you get a cleaner sight picture without distracting shine. The traditional 3-dot notch and post geometry is intuitive for defensive presentations and transitions—familiar enough for any shooter but purpose-built for speed and accuracy when visibility drops.

Built in Fort Worth, Texas, these sights are engineered for Glock's compact 42, 43, 43X, and 48 platforms. Whether you carry a slim single-stack daily or stock multiple guns, this 20-count pack keeps you supplied with night sights that combine passive glow with active tritium so you're never reliant on a single light source.
