The GLOCK Training pistols were developed for the purpose of enabling reality-based tactical operations training with color marking or plastic bullet ammunition. Designed specifically for use with UTM Ammunition, this optic ready pistol offers the same ergonomics and touch-and-feel which officers and soldiers are familiar with their service pistol. This GLOCK Safe Action^® training pistol is distinctive blue with a revolutionary slide with polymer inserts in order to make it visually distinct and light weight. This distinctive color keeps the training pistol from being mistaken for a live fire weapon.
