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.

Frequently Asked Questions

Will these night sights work on my Glock 43X or 48?

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

Can I install these myself, or do I need a gunsmith?

XS designed the R3D 2.0 for DIY installation. The sights require 50% less installation force than the original R3D, so most shooters can install them at home with basic tools. If you're unsure, a gunsmith can install them quickly.

How bright are these sights in low light?

The front sight is dual-illuminated with both tritium and photoluminescent material. The tritium glows passively in darkness, while the photoluminescent green glow dot charges from ambient light or flashlights. The blacked-out rear sight creates high contrast, making the sight picture pop even in dim conditions.
