Trijicon SA04 - S&W 9mm with Fixed Rear, 3 dot green front & green fixed rear night
sight set.

This model is for gun made before Novak sights (before late 1989).
It fits models 5903, 5904, 5906, 915 and 411.

Green lamps are warranted for 12 years from the date of manufacture. Trijicon offers a choice of illuminated dot colors, to suit individual shooter preferences.

Trijicon Night Sightsare available with green, yellow, and orange aiming dots. The front sight is only available with a standard illuminated green dot. 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 3 Dot Bight Sight Setsare 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 Sightsare the brightest, best and safest.
