My 4th pistol that models the beretta M93r(raffica which means burst)because of the barrel and slide,and the Glock 18(compensator and full auto "fire"). the gun doesn't fire anything.The selector switch is up for safe,middle for semi,and down for full auto(that was the positioning).The gun has blowback which moves back 4 studs.The gun also has a working hammer that is external(just flip it up and move the slide,it will reset it).Enjoy the pictures!Pics 3,4,5 are the fire selector.
