Phuc Long is here to tell you the History Of the Glock while firing his Grey Glock 19. The Glock is debatably the best hand gun ever made and can be fired in many adverse conditions. Including being fired upside down. He even takes aim at a target and hits it everytime, but that just turns out to be someone hitting a bell right next to the gun. Very interesting to know I can fire my gun upside down.
