New Brite-Site TFO 1911 Handgun Sight Models From TruGlo


Geneseo, Illinois –-( TRUGLO Inc., manufacturer of the world’s most advanced line of fiber-optic sights and accessories for the shooting sports industry introduces its NEW! 1911 MODELS for the BRITE-SITE TFO (Tritium/Fiber-Optic) family of handgun sights.

The new 1911BRITE-SITE TFO handgun sight models include Novak Lo-Mount cut sights for the 5” Government in .45ACP, 9mm/.40 S&W, as well as the 3” Officers and 4.25” Commander models in .45ACP, 9mm/.40 S&W. These new sights offer revolutionary innovation with TRUGLO’s patented combination of TFO (Tritium and Fiber-Optic) technology delivering an enhanced sight picture 24/7.

Rapid target acquisition is achieved with TFO technology by utilizing existing ambient light to illuminate the sight picture during bright lighting conditions and then utilizing the tritium component to illuminate the fiber-optic during low light or no light conditions.

The patented TFO technology offers an uninterrupted, consistent sight picture for the shooter when other sight systems fall short.

The low profile sight housings are constructed from CNC-machined steel. The technical design protects the fiber while concealing its view from the target. The TFO sights fit in standard holsters and are designed to be snag-resistant and dependable. Each set is available in a green front sight /green rear sight combination or a green front sight / yellow rear sight combination.

I need fibroptic sights for my Ruger 1911 10mm target pistol with a 5 in. barrel.I would like to keep the rear adjustable sight that came with the pistol and change the front to fibroptic. please advise me on this.


james did they anwser you about those sights? i have R.I. 1911 a1 cs with the novac style sights that come stock on it and want these but dont know if they will fit

james barrett

A lot of us out here do not like a rear sight that distract from the front or is not adjustable.. Why can we not get just the front TFO sight for a Novak cut 1911.


Need sights for 1911 with 4 inch barrel and slide has dovetail cuts in slide front and back and wondering if your TRU GLO sight set (TG131NT3 /TG131NT3Y) sight’s will fit my pistol, and if so how much in price for either set. JERRY (717) 300 3778
