XS Sights R3D Night Sights for Glock 36 - 3-Dot Tritium Green/Orange Outline Front, Green Tritium Rear

The XS Sights R3D Night Sights deliver a traditional 3-dot tritium sight picture to your Glock pistol, engineered for fast, intuitive target acquisition in any lighting. The set uses a square notch-and-post design with a wider rear notch so the eye locks onto the front sight first, helping you press the trigger with a clean sight picture under stress.

The front sight carries twin green tritium vials wrapped in a bright orange outline ring that draws the eye in low light and transitional lighting. The rear sight pairs matched green tritium vials in a wider notch, and the rear body is blacked-out to maximize contrast against the illuminated front dot. The result is a classic 3-dot sight picture that stays visible day or night without being washed out by weapon lights or streetlights.

Sight bodies are CNC machined from steel with a black finish for the durability and corrosion resistance a defensive pistol demands. The set is sized and contoured specifically for the Glock 36 slide and drops into the factory sight cut for straightforward installation.
