Frequently Asked Questions
Will these sights fit my Glock 17 as well as the Glock 19?
Yes. The XS R3D 2.0 sights in this listing are compatible with both the Glock 17 and the Glock 19, as these models share the same sight dimensions. If you own a different Glock model, verify the sight cut specifications against XS Sights' compatibility chart before purchasing to ensure a proper fit.
Do I need a gunsmith to install the R3D 2.0 sights?
Not necessarily. XS Sights rates the R3D 2.0 as DIY-installer friendly, and the second-generation design requires 50% less installation force compared to the original R3D sights. Most users can install them at home with a standard sight pusher tool. However, if you're not comfortable working on your firearm, a qualified gunsmith can have them installed quickly and safely.
How do tritium night sights differ from fiber optic sights, and which is better for low-light use?
Tritium night sights use a small self-luminous tritium vial that glows continuously without any external light source, making them reliable in complete darkness. Fiber optic sights, by contrast, gather and amplify ambient light but go dark in low-light or no-light conditions. The R3D 2.0 combines tritium with a photoluminescent "Glow Dot" coating that charges in daylight and glows green in low light, giving you the best of both worlds — exceptional brightness in the day and dependable visibility at night.
