Tapco TAP22040 Tritium Sight Black Frame Fits Glock 17/17/19/22-28/31-35/37-39/45/48
The Tapco TAP22040 tritium sight gives your Glock a reliable, low-light aiming solution without batteries or external power. Built around self-illuminating tritium vials, this black-frame sight stays visible in darkness, low-light rooms, or heavy cover—conditions where traditional iron sights fade. If you shoot defense, duty, or night-ready carry, tritium sights are the field-proven answer to the "can I see my sights?" problem. Tapco's design fits a broad range of Glock models, making it an accessible upgrade for shooters who want their irons to work when it matters most.
Tritium glows continuously without charging—there's nothing to activate, no green laser battery running down in your holster. The sights maintain visibility for years, long enough to outlast most shooter preferences or holster wear. For Glock users who value speed and reliability in defensive or sport shooting, adding a tritium front and rear pair removes one variable from the shot process: knowing exactly where your point of aim is, any time of day.
This is straightforward hardware. Tapco sights are made to function, not to be flashy. They're compatible with standard Glock dovetail cuts across a wide range of models—from the ubiquitous G17 and G19 to service-sized pistols in the 22–28 and 31–35 families, plus the newer slim-frame 45 and 48. If your Glock is in that lineup, these sights slot in without fuss. Black anodizing blends with modern Glock aesthetics and resists corrosion in daily carry or duty use.
