XS Sight Systems F8 Night Sight Set for Large Glock - Orange Glow Dot Front / Wide Notch Rear

The XS Sight Systems F8 Night Sight Set is a purpose-built tritium night sight upgrade designed for full-size Large Glock pistols. Built around the signature XS Figure 8 sight picture, this set pairs a large 0.160" high-contrast front post with an oversized wide-notch rear sight so the eye locks onto the front sight instantly in defensive, duty, or carry use.

The front sight features an Orange Glow Dot that absorbs ambient light and re-emits it in low-light conditions, giving the shooter a visible aiming reference even before the tritium takes over. The rear sight uses a tritium dot with a blacked-out wide notch, eliminating distracting daylight glare around the front blade and producing a clean, high-contrast sight picture that works equally well in bright sun or dim indoor lighting.

Powered by tritium in both the front and rear elements, the F8 set glows continuously for 10-15 years or more without batteries or the need to charge the sights under a light source. The set is compatible with Gen 1-6 Large Glock pistols and is designed for easy hand installation with no special tools or gunsmithing required, making it a straightforward drop-in iron-sight upgrade for your Glock.
