The Meprolight Tru-Dot tritium sight set for 1911 pistols brings self-illuminating night sights to your carry or range gun without batteries, switches, or charging. This steel blue finished set pairs a wide tenon front sight with a Colt-pattern rear cut, delivering a true green-on-green three-dot sight picture that functions in complete darkness. Tritium gas tubes built into both front and rear blades glow continuously, making target acquisition and sight alignment possible when conventional sights disappear in low light. Whether you're a competitive shooter, defensive shooter, or someone who values reliable performance in any condition, these sights deliver the edge when visibility matters most.
The Tru-Dot design has proven itself across military and law enforcement use, and the engineering is straightforward: no electronics to fail, no maintenance rituals, no power management. The sights are immune to solvents, oils, weather, and the wear that comes with hard use. The green tritium front sight is calibrated for contrast against the rear sight, making the aiming point obvious even in near-total darkness. These sights ship complete—everything you need to upgrade your 1911 is in the box.
Installation on 1911-pattern pistols is direct: the wide tenon front sight replaces the factory front, and the Colt rear cut fits standard 1911 rear dovetails. If you're upgrading an older carry gun or building a new one, this is a proven path to low-light capability that doesn't rely on technology or upkeep.
