Tapco Tritium Sight Black Steel Frame for Glock 17/19/22-28/31-35/37-39/45/48

The Tapco Tritium Sight delivers bright, always-on aiming dots for low-light and nighttime pistol work. Built around a steel frame with a durable black finish, these self-illuminating night sights rely on tritium to keep their glow active around the clock without batteries or external light charging.

Engineered specifically for Glock handguns, the TAP22040 fits one of the broadest ranges of Glock pistols on the market, including the Glock 17, 19, 22-28, 31-35, 37-39, 45, and 48. That wide compatibility covers numerous duty and carry platforms, making it a versatile upgrade for shooters who run more than one Glock.

Tapco's tritium sights are designed to offer brighter, more vivid aiming dots than typical factory three-dot iron sights, giving the shooter quicker sight acquisition and a clearer reference point in dim conditions. The tritium inserts glow continuously, providing an immediate visual reference whether the pistol is drawn from a holster at dusk or used for home defense in the dark.

Installation is straightforward: the rear and front sight assemblies install directly on the slide as a replacement for factory sights. Once installed, the sights require no activation or maintenance - just reliable aiming reference whenever the pistol is in hand.

Whether you carry concealed, run duty shifts, train in low-light environments, or simply want a faster sight picture at dawn and dusk, the Tapco Tritium Sight gives Glock owners a dependable low-light aiming solution backed by rugged steel construction and the proven self-illuminating technology of tritium.
