The Trijicon Suppressor/Optic Height Sights (brand part no. GL243-C-601143) continue the low-light and no-light performance of Trijicon’s original Bright & Tough Night Sights, built for Glock 42/43/43X Slim Frame pistols fitted with a suppressor and also usable as a backup iron sight for a pistol-mounted red dot. The front sight is green tritium with a yellow outline; the rear is green tritium with a black outline and a square notch. Each lamp is housed in a metal body cushioned in silicone rubber for a shock-resistant design, capped with a sapphire jewel that evenly distributes light while protecting the lamp from solvents and puncture. Trijicon recommends professional installation.
