Glock 17,19 rear sight. Glock Steel sights provide a more robust alternative to the regular polymer sights. This sight was designed to withstand the wear and tear of frequent work with a holster. The sight has the well-known GLOCK sight pattern in white. The rear sight is mounted to the slide with the help of the Glock rear sight mounting tool, which allows you to easily swap the sight for one of a different height or type. Changes of elevation or type are made by switching out the front sight.
