Truglo TFO Tritium/Fiber-Optic Day/Night Sights Fits Glock 17 / 17L 19 22 23 24 26 27 33 34 35 38 and 39 – Front Green/Rear Green

Day-and-night shooting demands sights that work when natural light fails and when it doesn't. The Truglo TFO combines tritium self-illumination with fiber-optic brightness in a single 3-dot setup built for common Glock frames. Whether you're in San Ramon or across the South Bay, TacticCAL supports shooters with proper FFL transfer in Sunnyvale and transfer services.

Dual-light technology for variable conditions

Tritium and fiber-optic sights handle opposite lighting scenarios. Fiber-optic collects ambient light during day and overcast shooting, while tritium glows independently after dark without batteries. The green front and rear configuration gives you a consistent sight picture across dawn, dusk, and indoor low-light work. This pairing eliminates the need to swap sights or carry backup aiming systems. Front and rear set installation is straightforward on the listed Glock models, making upgrade simple for shooters who already run standard frames. For other platforms, explore PC §32100 exempt revolvers and alternative sight systems. TacticCAL is your local firearms dealer in the Bay Area.

Frequently asked questions

How bright is the fiber-optic element in indoor or heavily shaded environments?

Fiber-optic brightness depends on available ambient light. Indoors or in shade, tritium takes over as the primary light source, ensuring the sight remains visible. This is why dual-illumination sights work across varying conditions without gaps in usability.

Can I install these sights myself, or do I need a gunsmith?

Glock sight installation typically requires a sight pusher tool and basic mechanical skill. Many shooters handle it themselves; others prefer professional installation to ensure proper alignment and avoid cosmetic marks. TacticCAL staff can discuss your options.
