The CO2 airgun replica of the Glock 19 is compact and handy, with the unmistakable look of the original pistol and plenty of power. In spite of its relatively small length of 7.25 inches, it fires .177 caliber steel BBs with a muzzle velocity of up to 410 FPS and weighs a satisfying 25.6 ounces. In true Umarex replica form, it has a metal slide and a trigger blade safety.
