The Operator style ritium night sight for Glock pistols featrues a thin front blade and the traditional three dot tritium system. The Operator has the white-outline ring on the front sight only, resulting in quick acquisition of the front sight. In low light, the rear tritium dots are visible, but no white outlines on the black rear sight make the AmeriGlo sight ideal for those needing tritium sights and a quick-to-find front sight. The added 'daylight' on the sides of the front sight during sight alignment make the sight quick to use, especially for those shooters having trouble finding their front sight in rapid shooting drills.
