XS SIGHTS 3-Dot Tritium Night Sights for Glock Gen 1-5 - Fast

In this review the XS SIGHTS 3-Dot Tritium Night Sights are evaluated for Glock owners who need a durable, highly visible sight set that works day and night. The bottom line: these sights are best for shooters who want a straightforward, battery-free upgrade that improves front sight focus and quick target acquisition, especially in low light. Installation is DIY friendly and they fit a broad range of Glock models, so the biggest reason to buy is the consistent, self-illuminating tritium/photoluminescent front dot that delivers a clear sight picture without electronics.

Key Features

• Model Compatibility: Fits Glock 17, 19, 22-24, 26, 27, 31-36, and 38 including MOS and Gen 1 to 5 pistols, giving wide interchangeability for Glock owners.
• Always-On Illumination: Self-illuminated tritium glows 24/7 for a bright, battery free sight picture in low light conditions.
• Enhanced Front Visibility: The orange photoluminescent glow dot paired with tritium makes the front sight easy to pick up quickly in day or night shooting.
• Anti-Glare Rear: The blacked-out rear sight reduces distraction and drives focus to the front sight for faster alignment.
• Rugged Construction: CNC machined from solid steel for a durable, dependable replacement for factory sights that holds up under use.
• Practical Design: Rear sight ledge allows one-handed slide manipulations for everyday carry handling and clearing techniques.

Who It's For

The XS SIGHTS set is best for Glock owners who want a no-nonsense night sight replacement that improves speed and visibility without batteries or electronics. It suits concealed carriers, range shooters, and anyone who values an easy DIY install and long-term durability in a sight set that fits many Glock models.

Shooter types who should look elsewhere include those who need adjustable or specialty competition sights, or users who prefer fiber optic-only daytime sights; this set emphasizes tritium night visibility and rugged iron construction rather than ultra-fine target adjustments.

Pros & Cons

Pros

• Excellent low-light visibility from the tritium plus orange photoluminescent front dot.
• Durable CNC machined steel construction replaces fragile factory sights for long service life.
• Wide compatibility with Glock Gen 1-5 pistols including MOS models, and easy DIY installation.
• Blacked-out rear sight focuses the eye on the front for faster sight acquisition.

Cons

• Not adjustable for windage/elevation like some target sights, so zeroing requires slide drift or gunsmithing if needed.
• Large front dot may be too prominent for shooters who prefer very small sight dots for precision target work.
