The XS Sights R3D 2.0 night sights for Glock 43X/48 are purpose-built for shooters who need fast, reliable sight acquisition in any light. These green 3-dot sights combine a dual-illuminated tritium front sight with a blacked-out serrated rear, giving you the contrast and speed that matter when it counts—whether you're running drills at the range, training for defensive scenarios, or carrying daily. The R3D 2.0 represents XS's second-generation design, engineered to be brighter and more durable than the original.
What sets these apart is the thoughtful engineering: the front sight uses both tritium and photoluminescent material for brightness in low light and daylight, while the rear sight is serrated and blacked out to eliminate glare and keep your focus downrange. The rear sight ledge lets you manipulate the slide with one hand if you need to. Installation is straightforward for a DIY job—XS redesigned the R3D 2.0 to require 50% less installation force than earlier versions, so you don't need gunsmith-level leverage to get them on. The black nitride finish stands up to years of carry, training, and hard use.
These sights are an upgrade path for Glock 43X and 48 owners who want brighter, faster sight pictures without sacrificing durability or reliability. The green photoluminescent glow dot is visible in low light and charges naturally from ambient light or tactical flashlights.

Yes. The XS Sights R3D 2.0 is engineered specifically for the Glock 43X and 48.
