Truglo TFO Pistol Sights – Lighting the Way Day or Night

Last Updated on January 12, 2021.

When Truglo set out to combine the glow of a night sight with the brightness of a fiber optic they created the TFO pistol sight.  The Tritium Fiber Optic sight was a unique new design combining these two elements, and can be installed on many pistols without any modification to the firearm itself.  TFOs provide a clear and bright sight picture no matter the time of day or lighting condition.

The main feature of the TFO is the combination of tritium, from a night sight, and light gathering fiber optic tubes which gather daylight to increase brightness.  The tubes are set inside of a CNC-machined steel body for strength.  They are coated in Truglo’s “Fortress Finish” to help protect against wear and tear during use.

The TFO sights will fit holsters without modification, allowing you to use gear you’re already familiar with.  While Truglo has released newer sights with TFO technology, the TFX and TFX Pro, the original TFO sights are still very a popular choice.

Scope Review and Breakdown

TFO sights offer some nice upgrades over regular pistol sights. The tritium inserts glow in low light conditions, which is useful to those needing a night sight. 

They do not require additional light or batteries to function.  The fiber optics transmit light from the top openings to the 3 dots, allowing the sight to glow bright green for fast aiming and ease of use during the day.

Unlike the TFX model there is no contrasting focus ring around the front sight, an option which many shooters may prefer.  The TFOs are a 3-dot design with a green front sight and green rear sight.

They are also available with a green front sight and yellow rear sight depending on shooter preference.  Models are available to fit many of today’s popular pistols.

    Our Opinion

    Truglo TFO

    If you are looking for a pistol sight with TFO technology without spending a ton of money, these are a good choice. 

    The TFO inserts are easy to see no matter the lighting condition.

    They even work great outside during bright daylight hours.

    The construction isn’t as strong as the TFX sights but for occasional use there shouldn’t be any issues. 

    The TFOs are fun to shoot with, easy to see, and will provide years of enjoyment on your favorite pistol.

    Other Options Worth Looking At

    If you need a robust sight to withstand heavier use, we would recommend either the TFX or TFX pro sights from Truglo.  They have taken user feedback from the TFO and implemented several upgrades over the original sight.  They are more expensive however.
