XS Sights R3D 2.0 Night Sights for S&W M&P Shield – Optic Ready, Green Tritium Front

The XS R3D 2.0 night sight set delivers a high-contrast sight picture for S&W M&P Shield pistols equipped with optic cuts. The green tritium front sight glows in low light without batteries, while the blacked-out rear notch eliminates distractions and drives focus to the front dot. This configuration is designed for shooters running red dot optics who want a reliable backup iron sight setup.

Machined from steel with a durable finish, these sights are purpose-built for the Shield's optic-ready slide profile. The front sight's shallow V-notch rear design promotes rapid target acquisition in defensive shooting scenarios. Installation requires sight pusher or gunsmith services; front sight may require staking or thread locker depending on pistol generation.
