👁️ Oversized XXX Glow Inserts

Unlike traditional three-dot sights, TSA® XXX sights feature oversized X-shaped photoluminescent inserts that create a bold, highly visible sight picture.

The larger glow inserts are easier to recognize during rapid presentation, defensive shooting, and low-light conditions. The unique XXX pattern also helps visually separate the iron sights from your optic's reticle, allowing for faster sight alignment during co-witness use.

These are photoluminescent glow sights—not tritium sights. The inserts quickly charge from sunlight, indoor lighting, or a flashlight, producing a bright green glow in darkness.

Glow intensity is strongest immediately after charging, gradually fades over time, and can be recharged indefinitely with additional light exposure.

Product Description

The TSA® XXX Glow Sights are a precision-engineered upgrade for a wide range of Glock® pistols, including Gen 1-6 and MOS models. Built around TSA's distinctive oversized XXX aiming system, these sights deliver a bold, intuitive sight picture that outperforms traditional three-dot designs in both daylight and low-light conditions. Photo-luminescent "X" inserts charge rapidly from sunlight, indoor lighting, or a flashlight, then emit a bright green glow in darkness — no tritium, no batteries, and no electronics required. Machined from aircraft-grade 7075-T6 aluminum and finished with MIL-SPEC Type III hardcoat anodizing, these sights are built to withstand everyday carry and demanding range use. The package includes a front sight, rear sight, high-strength carbon steel front sight screw with pre-applied threadlocker, a low-profile front sight nut, and a 3/16" thin-wall front sight installation tool — everything needed for a straightforward installation. Compatible with Glock® 17, 19, 19X, 20, 21, 22, 23, 26, 27, 34, 45, 47, 49, and many Glock-pattern pistols. Not compatible with Glock® 42, 43, 43X, or 48 Slimline models.
