If you’ve ever stared at your factory Glock sights and thought, “Surely we can do better than plastic ‘ball-in-a-box’,” you aren’t alone. Glock sights are the “placeholder tires” of the gun world—functional, but the first thing most of us swap out.

Enter the XS Sights New Optic Height Fiber Optic Sights. These aren’t just another set of irons; they are specifically built to play nice with the red dot revolution while keeping things bright and punchy.

What’s the Deal with These Sights?

XS Sights has moved beyond just “Big Dots.” This new set features a high-visibility fiber optic front (available in green or red) paired with a serrated, blacked-out rear.

• Optic-Ready Height: These are tall enough to give you a “Lower 1/5th” co-witness. This means they stay out of the way of your red dot’s window but are right there if your battery decides to quit mid-drill.

• Built Like a Tank: Unlike the factory plastic, these are CNC-machined steel. They’ll survive a slide rack off a belt or a barricade without flinching.

• Light-Hungry Design: The front sight has an open-top cradle that lets in an impressive amount of ambient light, making that fiber rod glow even on overcast days.

Is It the Right Choice for Everyone?

I answer that question in my review…
