Although commonly called the “Schmeisser” after German room broom engineer Hugo Schmeisser, the inventor of the MP18 and MP28 sub guns– among the first generation of the type– the Maschinenpistole 40 was actually designed by Heinrich Vollmer as an upgrade to his own MP36 and EMP-35 series guns.
While some researchers have showed that much of Vollmer’s design could be inspired by previous work done by Schmeisser, nonetheless, it is Vollmer’s name on the patent. Schmeisser held the patent on the weapon’s magazine, which he had designed for his own unsuccessful wooden-stocked MP41. Nevertheless, Allied troops examining captured examples of the MP40 in World War II took to calling it “The Schmeisser” and the name stuck.
But no matter what you call it, as the above video from the VSO Gun Channel shows, the 8.75-pound MP40 can spray 9mm at 500 rounds per second like a garden hose.
