Truglo TFX Pistol Sights – Ready Day or Night

Last Updated on January 9, 2021.

What if you could have the benefits of a night sight with the easy to see glow of a fiber optic for daytime shooting?  Truglo revolutionized this concept with the TFO sights a few years ago.  Now, utilizing feedback from shooters everywhere, they have released an upgraded version of the TFO – the TFX Day/Night pistol sight.


  • Easy to see day or night. The TFO inserts are bright, clear, and allow for precise targeting
  • Durable construction and finish
  • Wide variety of models available for popular pistol choices
  • Fits standard holsters without modifications
  • Sealed capsule protects the sights from oils, chemicals, and debris


  • Longer than normal sights, does reduce sight radius slightly
  • Fiber Optics always have the possibility of coming loose
  • Must be installed using special tools or by a gunsmith - adds to cost

Utilizing the new upgrades, the TFX is more compact, sleeker, and more robust than the original TFO sight.  The combination of tritium and fiber optics gives you a bright sight picture any time of the day or night.  The new sight housing protects against oils, debris, and containments and is extremely resilient.

The TFX has also been designed to fit any standard holster you may already have for your pistol without modification.  This is a huge benefit and can save the shooter hundreds of dollars in the long run. With the combination of new features and durability, the TFX is a fantastic pistol sight.

Sight Review and Breakdown

The TFX offers several benefits over a standard pistol sight.  The tritium inserts allow for use at night or in any low light condition.  The fiber optics gather natural light and allow the sight to glow during the day for quick target acquisition.  Additionally, there is a small ring around the front sight that allows the shooters eye to focus more easily.

The TFO inserts are housed in a hermetically sealed capsule to protect them from any sort of chemicals and solvents.  These sights are built using Truglo’s new “Fortress Finish” and CNC steel which has been designed to be virtually unbreakable.  

Unlike other fiber optic sights that can be fragile, you won’t have to worry about damaging the TFX while using a holster or firing your weapon.

The TFX sights are available for dozens of popular pistols, including Glock, Smith & Wesson, 1911s, and Sig Sauer.  Some models are available in suppressor height versions as well.

1. The TFO technology is a combination of fiber optics and tritium. This allows these sights to glow 24 hours a day, giving the shooter a bright sight picture and quick alignment.

2. The CNC Machined Steel and “Fortress Finish” ensures that the sights will withstand thousands of rounds of firing, as well as being tough enough for field use and holstering without issue.

3. The sealed chamber keeps oils, dirt, and chemicals out of the sights. This makes for quicker and easier cleaning of your firearm after use, and will ensure the sights glow as they should for a long time.

4. The snag-free design allows these sights to be used with any standard holster you may already have without modification.

Our Opinion

If you are looking for a unique pistol sight that does a little bit of everything, the TFX is a great choice. 

The “always on” glow of the TFO inserts is easy to see, even in bright daylight.  

The construction means you don’t have to worry about over use or chemicals affecting the sights during cleaning. 

The wide variety of models means there should be an option for whatever pistol you want install these on.  

These are fantastic pistol sights, and are well worth your consideration.

Other Options Worth Looking At

These sights are very unique, and there aren’t many things like them on the market today.  The original model TFOs are still available from Truglo.  While these aren’t as durable as the TFX, they are less expensive and are a great option for a pistol that is not going to be used as much or carried daily. 

Trijicon is making night sights with a similar bright front focus ring, but these do not have the fiber optic insert so will only glow at night.  They can be found for under $150.
