TruGlo Glock 20/21 Fiber Optic Sight Set

The TruGlo Glock 20/21 Fiber Optic Sight Set is the higher-profile Glock version of TruGlo’s red-front, green-rear fiber sight system. Ambient light makes the three aiming points stand out without batteries, while the contrasting colors help the shooter pick up the front sight quickly. This configuration is aimed at the larger .45 Auto and 10mm Glock application group, including Glock 20 and 21 pistols.

Protected fiber rods are housed in a compact sight profile that remains practical for normal handgun use. The sight picture stays mechanically simple, with no switches or illumination settings to maintain. Fit should be checked carefully on Glock 36 and 30S variants because TruGlo notes model-specific compatibility considerations within the high-profile application group.

This high-profile set is intended for the Glock 20 and 21 family rather than the more common low-height Glock sight group. TruGlo advises extra fit verification on Glock 36 and 30S pistols because slide relief can affect front-sight clearance.
