XS R3D Night Sights for Smith & Wesson M&P Shield

XS R3D Night Sights: Designed for Low-Light Performance

The XS R3D night sights represent a thoughtful approach to defensive sight design. Built around the proven 3-dot tritium concept, these sights combine traditional notch-and-post geometry with modern photoluminescent technology.

Key Features

• Tritium Front Sight with proprietary green Glow Dot that absorbs ambient light and glows in darkness
• Blacked-Out Rear Sight with tritium vials that illuminate without overwhelming the front sight
• Optimized Brightness Ratio keeps your focus on the front sight for faster target acquisition
• Proven 3-Dot Design familiar to shooters of all experience levels

How It Works

The R3D system uses a brighter tritium vial in the front sight, which charges the photoluminescent Glow Dot slightly. This creates a natural brightness hierarchy—your front sight glows more brightly than the rear tritium vials. The result is faster sight alignment and better focus downrange, whether in daylight or complete darkness.

Specifications

Front Sight: 0.440" length × 0.145" width × 0.282" height

Rear Sight: 0.890" length × 0.800" width × 0.380" height

The Bottom Line

These sights deliver reliable, visible aiming points in any lighting condition. Whether you're at the range or preparing for defensive readiness, XS R3D sights keep you ready for the fight.
