The UMA Glock 19 is ideal for a more versatile role because of its reduced dimensions. The CO2 airgun replica of the Glock 19 in .177 caliber is compact and handy with the unmistakable look of the original pistol and plenty of power. This Semi-auto repeater model is powered by one 12g CO2 capsule, the CO2 is housed in the grip and the CO2 Allen Key is integrated into the backstrap. It has a metal slide, fixed Glock style sights, integrated Weaver rail and a push button safety in the trigger.
