XS Sights R3D 2.0 Suppressor Height Night Sights for GLOCK 19 – Green Tritium Front

The XS R3D 2.0 suppressor height night sights deliver fast target acquisition with a green tritium front sight and blacked-out rear. Designed for GLOCK 19 pistols equipped with red dot optics or suppressors, these sights provide a lower 1/3 co-witness and maintain functionality if your optic fails. The tritium insert glows in low light without batteries, while the high-contrast green front sight draws the eye immediately in any lighting condition.

Built for duty and defensive use, the R3D 2.0 features a notch and post sight picture with a wide rear notch for rapid sight alignment. CNC-machined steel construction ensures durability under recoil and hard use. Installation requires a sight pusher tool or professional fitting. These sights clear most suppressor heights and allow you to maintain iron sight capability alongside slide-mounted optics.
