Z84

The Z84 is a Spanish machine pistol created by the Star Bonifacio Echeverria of Spain. It is an automatic pistol firing a 9×19mm parabellum round. Its operating mechanism consists of a blowback system with a telescoping bolt, this helps keep the dimensions short making it more compact. This makes it a favorite of Spanish security personnel

Rather similar in appearance to many other machine pistols of the time, it has a metal stock that can be folded on top of the weapon as well as a safety switch on the trigger. It was later configured to fire a wide variety of ammunition types, and thanks to the 600 rpm rate of fire, it is more manageable than other similar machine pistols. The Ingram MAC-10's rate of fire for example is 1,100 rpm.
