The Spartan Tactical Night sights have multiple tritium vials placed by Trijicon. This AmeriGlo Glock sight set has a single green tritium insert in the front as well as two tritium inserts in the back. This give you the standard 3-dot sight picture that many users are familiar with. Tritium is a radioactive material with self luminous properties. What this means is that these tritium vials give off their own light without having to be “charged” by day light or powered by an external battery source. Even if the tritium never sees the light of day, they will glow continuously and have a half life of approximately 12 years.
Made to Be Used in High Stress Situations
The AmeriGlo Spartan Operator Glock sights have several design features that make them ideal for a defensive pistol. The front sight features a very large, bright orange ring around centered tritium insert. This orange outline is designed to be easy to find and grab your attention. This makes sight acquisition much easy when in a stressful situation. The rear sights are also blacked out w/ tritium inserts. This minimizes other distractions and allows you to focus fully on the front sights, which is the aiming method most firearm instructors teach.
