The XS Sights R3D night sight set is a high-visibility option for Glock 42, 43, 43X, and 48 pistols. Built around a traditional 3-dot sight picture, these night sights combine tritium and photoluminescent technology to keep your firearm visible whether you're shooting in daylight, low light, or complete darkness. Each sight features a tritium element for reliable nighttime glow and a photoluminescent glow dot that charges from ambient light, giving you backup illumination when tritium alone isn't enough. The rear sight has a wide notch design with an anti-reflective lens coating that cuts down on glare and helps your eyes focus on the front sight — the fundamentals that matter for quick, accurate shooting.
This is a genuine alternative to factory Glock plastic sights, designed to be more durable and more visible in defensive or hunting scenarios where light is limited. XS Sights manufactures these in Fort Worth, Texas, so you're supporting a US-based optics maker. The kit comes as a bulk pack of 20 complete sight sets, making it ideal for a range that shoots multiple Glock pistols, a law enforcement outfit, or a dealer stocking popular models.
Installation requires gunsmith tools and knowledge; these are not factory press-fit sights. If you're new to sight replacement, have a qualified gunsmith handle the job to ensure proper sight picture and safety. The green color is a factory identifier (the sight elements are still tritium-powered regardless of housing color), so confirm the model compatibility with your specific Glock variant before ordering.
| Brand | XS Sights |
| Product | R3D Night Sight Set |
| Fit | Glock 42, 43, 43X, 48 |
| Sight Type | Tritium + Photoluminescent |
| Sight Picture | 3-Dot |
| Quantity | 20 Complete Sight Sets |
| Manufactured | Fort Worth, Texas, USA |
These sights are machined for Glock 42, 43, 43X, and 48 models. Verify your pistol's model before ordering to ensure proper fit. Glock slide cuts vary by generation, so if your gun is an unusual variant, check with your gunsmith.
XS Sights are precision components that require professional installation tools and expertise. We strongly recommend having a qualified gunsmith install these sights to ensure proper alignment, secure fit, and safe function of your firearm.
Tritium has a half-life of about 12 years, meaning brightness gradually fades over time. The photoluminescent glow dot provides a secondary means of illumination and can be recharged by exposure to light, extending practical visibility in low-light conditions.
This pack contains 20 complete R3D night sight sets (front and rear sights), enough to outfit 20 pistols or to stock as a dealer/range inventory.
