Ameriglo Trit F/r For Glk 17/19 Grn

The AmeriGlo Trit F/R for Glock 17/19 Green is a tritium night sight system engineered for rapid target acquisition in low-light and no-light conditions. This front and rear sight set combines self-illuminating tritium lamps with luminescent paint, delivering visibility across the full spectrum of tactical and defensive shooting scenarios—from pre-dawn range sessions to night-time duty applications.

The system features green tritium vials paired with bright green outline geometry on the front sight, while the rear sight uses green tritium with white outline for clear sight picture alignment. Tritium requires no battery or external activation; it glows continuously for approximately 10–12 years through self-powered radioactive decay. The LumiGreen paint coating absorbs ambient light and fluoresces for roughly 10 minutes after light exposure, providing a secondary illumination layer during transitions between bright and dark environments. This dual-illumination approach ensures the sights remain visible whether you're transitioning from daylight to indoor venues or operating in complete darkness.

These sights are compatible with Glock 17 and Glock 19 platforms, making them a practical upgrade for concealed carry, duty, or range-training workflows. The green tritium/white rear combination is favored by shooters who prioritize speed and contrast under stress, as the color pairing reduces parallax sensitivity and accelerates sight alignment compared to monochromatic designs. For defensive shooters who operate across variable lighting conditions and demand sights that work without maintenance or batteries, this tritium system delivers both reliability and consistent performance.
