TRUGLO TFO Tritium Fiber Optic Sight Set for 1911 Government 9mm/.40 S&W Novak Cut - Green Front

The TRUGLO TFO Tritium Fiber Optic Sight Set brings low-light capability to your 1911 Government in 9mm or .40 S&W, bridging the gap between fast daylight shooting and reliable night work. This is a complete front-and-rear matched set with a green fiber optic front sight paired with a tritium-equipped rear, designed specifically for 1911s with Novak-cut dovetails. Whether you're running drills at the range, practicing defensive skills, or carrying professionally, these sights give you a versatile aiming solution that doesn't depend on batteries or a flashlight to work when the sun goes down.

The green fiber optic front sight collects ambient light brilliantly in bright conditions, making sight picture acquisition fast and intuitive. That same front sight is also equipped with tritium, so when daylight fades, the glow takes over—no adjustment, no guessing. The rear sight carries tritium as well, maintaining that three-dot sight picture from dawn into darkness. It's a hybrid approach that eliminates the weak link in pure iron-sight shooting: that awkward moment when light runs out and your eyes are still adjusting.

Installation requires a gunsmith with a Novak-cut 1911 and the tools to properly drift and stake sights. These are precision components built to precise tolerances, and proper fit matters for both accuracy and safety. Once mounted, they're durable, low-maintenance, and built to handle the recoil and handling of a working 1911. If you shoot a Novak-cut Government-frame 1911 and want iron sights that work around the clock, this set is designed to do exactly that.

Frequently Asked Questions

Will these sights fit my 1911?

These sights are designed for 1911 Government frames with Novak-cut dovetails and are rated for 9mm and .40 S&W. If your 1911 has standard GI dovetails or a different cut, these will not fit. Verify your 1911's dovetail style before ordering, and have a qualified gunsmith install them.

Do I need a flashlight to use these sights at night?

No. The tritium inserts glow on their own in low light and darkness, so you can see and align your sights without any external light source. The fiber optic front sight also works in daylight without tritium, so you get two distinct aiming modes in one set.

What's included in this set?

You receive a complete front and rear sight pair, both designed to work together as a matched set. Installation into Novak-cut dovetails requires a gunsmith and appropriate drift tools.

How bright is the tritium at night?

Tritium sights provide a reliable, self-illuminating glow sufficient for sight alignment in darkness and low-light conditions. They do not require charging and will glow for many years, though brightness gradually diminishes over time as the tritium naturally decays.
