XS Sights R3D 2.0 Night Sights for Glock 43X/48 - 3 Dot Orange

The XS Sights R3D 2.0 night sights for Glock 43X/48 are purpose-built for shooters who demand fast target acquisition in any light. These 3-dot sights pair a serrated, blacked-out rear sight with a dual-illuminated tritium and photoluminescent front sight to keep your focus downrange and your shots on target—whether you're at the range in daylight or relying on your EDC pistol in low-light conditions. The orange ring on the front sight delivers high contrast in both bright sun and dim environments, making these among the most versatile night sights available for compact Glocks.

Installation is refreshingly straightforward. Unlike many aftermarket sight sets, the R3D 2.0 requires 50% less installation force than its predecessor, making the job easier whether you're a seasoned armorer or installing sights for the first time. The black nitride finish resists corrosion and abuse, and the rear sight ledge is shaped to support one-handed slide manipulations—a feature that matters if you ever need to chamber a round with one hand. Build quality is tough enough for years of EDC carry and training abuse.

The dual-illumination system—tritium for low-light reliability and photoluminescent material for daylight brightness—means you're not betting your sight picture on batteries or tritium vials alone. The combination gives you a true low-light advantage without sacrificing daylight usability. If you shoot your 43X or 48 regularly and want sights that work as hard as you do, the R3D 2.0 is a practical upgrade that pays dividends on the range and off it.

The orange ring creates high contrast in both bright and dim conditions, making the front sight easier to locate quickly under stress or in varied lighting. This dual-purpose design helps with speed and accuracy across different shooting environments.

Does the rear sight have any special features?

The serrated rear sight is blacked out to reduce glare and keep your focus on the front sight. The rear sight ledge is designed to support one-handed slide manipulations, which is useful for tactical reloads or emergency situations.
