Glock GL04 3 Dot Green Front & Green High Rear Night Sight Set

Glock GL04 3 Dot Green Front & Green High Rear Night Sight Set This 3 dot set fits Glock models 20, 21, 21SF, 29, 30, 31, 32 and 37. Green lamps are warranted for 12 years from the date of manufacture. Trijicon recommends green dots because they are the brightest lamps. They are best for targets in low- and no-light shooting conditions. Trijicon 3 Dot 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.
