Who This Is For
The TruGlo TFO Novak sight set is ideal for 1911 Government owners who demand a versatile, high-visibility aiming solution — whether for everyday carry, home defense, or competitive shooting.

Frequently Asked Questions
Will these sights fit my full-size 1911 Government pistol?
Yes. This TruGlo TFO set is specifically designed for the 1911 Government frame and uses standard Novak-cut dimensions — a .260 front sight height and .450 rear dovetail. They are compatible with most major 1911 Government models from manufacturers such as Colt, Springfield Armory, Kimber, and Rock Island Armory. If your pistol uses a Novak-style dovetail cut, these sights should drop right in, though minor fitting by a gunsmith may occasionally be needed.
How do TFO sights compare to standard tritium-only night sights?
Standard tritium night sights rely solely on radioactive tritium gas to glow, which can appear dim in bright daylight. TruGlo's TFO (Tritium Fiber-Optic) technology adds a fiber-optic pipe that harvests ambient light during the day, making the sight appear significantly brighter than tritium alone. At night or in low-light conditions, the tritium element takes over automatically — no switching required. The result is a consistently bright, crisp aiming point across the full spectrum of lighting environments.
How long will the tritium element last in these sights?
Tritium is a mildly radioactive gas that naturally decays over time. TruGlo's TFO sights use high-quality tritium vials rated for approximately 12 years of reliable illumination before noticeable brightness reduction occurs. After that point, the fiber-optic component continues to function in daylight indefinitely — only the nighttime glow gradually diminishes with age. For most users, a 10–12 year service life is more than sufficient before considering a replacement set.
