Beretta sights are machined from solid steel that have a sapphire front lens that helps focus the light from the tritium gas filled lamps. The gas filled lamps are silicone cushioned to take years of use and come with a full warranty. The lamps glow bright green in the dark and have white outlines that show as white spots in the daylight. These sights are impervious to solvents and puncture and are user installable; meaning they require no gunsmithing.
