Turning a Suomi subgun into a 9mm sewing machine (VIDEO)

Colorado-based ECCO Machine has a great way of showing off prototypes. The above shows one of ECCO’s Vorticis 45 cans, a 13.8-ounce Titanium and stainless suppressor they say is designed specifically to reduce port noise on blowback guns, particularly in pistol caliber carbines. To show it off he zips a mag through a Suomi in style — a what?

Finnish firearm wonk Aimo Lahti crafted his Suomi submachine gun in the early 1920s in .32ACP, and it was adopted by the Finns in 9mm as the KP/-31 using either a 50-round coffin mag or a 71-round drum, and finally a 36-round double. The gun was well-liked and really successful– so much that the Soviets copied the drum for their PPD-40 and PPSh-41 after being on the receiving end of the Suomi’s 900 rpm burst during the white hell of the 1939-40 Winter War. Neighboring Sweden likewise cloned it in 9mm Browning Long for their own use.
