TRUGLO Fiber-Optic Handgun Night Sights for Glock High, Red Front Green Rear Steel Nitride

TRUGLO Fiber-Optic Handgun Night Sight is a compact, snag-resistant three-dot sight set that uses fiber-optic rods to deliver bright red front and green rear aiming points without batteries.

Engineered for Glock high-frame pistols, this BRITE-SITE sight set combines traditional fiber-optic light gathering with CNC-machined steel construction and a durable nitride finish. The three-dot color contrast (one red front, two green rear) helps you pick up your sight picture quickly in daylight and low-light environments while keeping a low profile that fits most standard holsters.

How does the fiber-optic system improve visibility?

The fiber-optic rods collect ambient light and concentrate it toward the shooter's eye so the dots appear brighter without any power source. That means consistent, highly visible aiming points in varied lighting conditions without battery maintenance.

• Red front dot for quick target alignment
• Two green rear dots for strong contrast and depth perception
• Lights up automatically with ambient light — no batteries needed
• Designed to stay bright in daylight and usable in dimmer conditions

Will these sights hold up to daily carry and use?

Yes — the sights are CNC-machined from steel and finished with a Nitride Fortress coating to resist wear and corrosion. The compact, snag-resistant profile reduces the chance of catching on holsters or clothing during draw and re-holster cycles.

• CNC-machined steel body for consistent fit and durability
• Nitride Fortress finish for surface hardness and corrosion resistance
• Concealed fiber placement prevents the target from seeing the rods
• Snag-resistant shape compatible with most standard holsters

Which Glock models are compatible with this sight set?

This TRUGLO set is sized for high-slide Glock models commonly used in duty and personal carry. It fits a broad selection of Glock calibers and models, though MOS-style slides are excluded.

• Compatible with Glock 20, 21, 29, 30, 31, 32, and 37
• Also referenced for compatibility with some 25, 40, and 41 models (verify fitment)
• Not compatible with Glock MOS models unless specified
• Designed to align with factory sight cuts for straightforward installation

How easy is installation and maintenance?

Installation follows standard rear/front sight replacement procedures and typically requires basic gunsmith tools or a qualified armorer. Maintenance is minimal since the sights rely on passive fiber-optic light gathering and a durable finish.

• Standard dovetail fit for compatible Glock slides
• Requires sight drift or set screws depending on pistol model
• Clean fibers with a soft cloth to maintain brightness
• No batteries or electrical components to service
