The TFO combination shines in bright sun and remains visible when the lights go out, and with no batteries required, you can count on a dependable glow when you need it most. Snag-resistant design and compatibility with standard holsters make these Truglo Tritium/Fiber Optic sights a practical upgrade for duty, competition, or personal defense handguns.
