MP-28: Hugo Schmeisser Improves the MP18
The MP-28,II, an evolution of the MP-18,I by Hugo Schmeisser, introduced a crucial double-stack, single-feed box magazine that became a standard for later SMGs. Key improvements include selective fire (semi/full auto) and an upgraded tangent rear sight. Despite its advanced design for the era, it saw limited official German adoption until WWII, finding greater export success internationally.
