Trijicon offers a choice of illuminated dot colors, to suit individual shooter preferences. Trijicon Night Sights are available with green, yellow, and orange aiming dots. Trijicon recommends green dots because they are the brightest lamps. They are best for targets in low- and no-light shooting conditions. However, because some shooters prefer greater distinction between their front and rear sights, Trijicon also offers yellow and orange dots for rear sights. Trijicon recommends yellow over orange for the rear dots because yellow is brighter, lasts longer, and therefore carries a longer warranty.Trijicon SA-30 Smith & Wesson Chief's Special 40 and 45 3 Dot Front & Rear Night Sight Sets are designed and assembled with the optimum combination of strength and safety. The patented aluminum cylinder and sapphire lens construction cannot be equaled. The brightness obtained from the tritium content is focused through the sapphire lens to give the maximum possible illumination. Because the sight blades are machined from steel rather than cast, their strength is unsurpassed. Trijicon night sights are the brightest, strongest and safest. Trijicon SA30 S&W Chief's Special 40 and 45 Night Sight Set has a replacement leaf for the factory adjustable sights.
