TruGlo Tritium Pro Features The TruGlo Tritium Pro sight set is purpose-fit for the CZ P09 pistol in 9mm Luger giving shooters a direct replacement sighting solution that performs in any lighting condition. In daylight the sights function as standard white dot sights for fast familiar target acquisition. Once ambient light fades the tritium vials inside the sights begin glowing green with a white outline on the front sight letting the shooter maintain a visible sight picture in low-light or no-light scenarios where a standard sight would disappear. This transition happens automatically with no switches or activation required since tritium is a self-luminous isotope rather than a light-charged phosphor. Because tritium glows continuously without batteries or external light exposure the TruGlo Tritium Pro remains ready at all times whether the pistol has sat in a holster for days or been carried through bright daylight into a dark building. The sight set is built with a steel frame finished in black giving it the strength to withstand the recoil cycling and holster wear a defensive or duty pistol experiences. For CZ P09 owners who carry or train in variable lighting conditions this TruGlo Tritium Pro set delivers a dependable always-on night sight upgrade for sale at GrabAGun.
