Frequently Asked Questions
How does Ember® Glow Dot Technology differ from standard tritium sights?
Standard tritium sights rely solely on radioactive tritium gas to produce a glow in the dark. XS Sights' Ember® Glow Dot Technology adds a photoluminescent layer that absorbs ambient light — indoors, outdoors, or under artificial lighting — and re-emits it as a bright glow. Crucially, the tritium lamp continuously charges the Ember dot, meaning the front sight glows significantly brighter than the rear at all times, naturally drawing your eye to the front post for faster, more instinctive sight alignment.
Which specific Glock models are compatible with the Large Frame R3D sights?
The XS Sights R3D Large Frame variant is designed to fit full-size and large-frame Glock pistols, including the G17, G17L, G19X, G20, G20SF, G21, G21SF, G34, G35, G40, and G41. If you are unsure whether your specific Glock generation or model is compatible, XS Sights provides a detailed fit guide on their website, or you can contact Goodland Guns for confirmation before purchasing.
Do R3D Night Sights require any special tools or gunsmithing to install?
Glock sights are press-fit into the slide and typically require a sight pusher tool or a bench vise with protective pads for proper installation and removal. While mechanically inclined shooters can install them at home with the right tools, professional installation by a qualified gunsmith is recommended to avoid damaging the slide or the sights. Improper installation can also affect zero and accuracy, so having a gunsmith perform the install is the safest route for most owners.
