The XS Sight Systems standard-dot tritium sights for Glock provide optimal front-sight visibility under all lighting conditions and allow you to quickly acquire the target under all shooting conditions. The Glock XS sight is compatible with all Gen 1-5 Glock 20, 21, 29, 30, 30S, 37, 40, and 41 models.
The Glock 21 night sights from XS Sight Systems are designed with a high-contrast front sight that automatically draws your vision to the dot, and the rear V-notch sight provides an unobstructed view of the front sight. The sighting dot remains clearly visible even under the most stressful circumstances when your focus tends to be drawn downrange. The white outline of the rear sight aids in fast target acquisition, and the sight’s wide field of view enhances the visibility of downrange targets. The differentiated front and rear sights with straight-line sight picture virtually eliminates the chance of confusing the front and rear sights.
The convex surface area of the Glock 21 night sights dot increases the light transmission of ambient light to intensify the sight’s photo-luminescent properties. The dot’s high-contrast color design immediately puts you on target, even in low light conditions. The low-profile, snag-free design has an outside diameter of just 0.140 inches, allowing you to carry your Glock comfortably and fits most holster designs. The sights are CNC machined from steel stock and come with a 10-year, no-questions-asked warranty.
The Glock 21 night sights are so simple to swap out with the factory-installed sights it can be done in just minutes. No special knowledge is required, and the sight ships with the Glock tool needed to change out the front sight.
