The MP 28/II is a German submachinegun chambered for a wide variety of calibres, though it is most often found in 9x19mm Parabellum. It is essentially an improved version of the MP 18, designed almost a decade later as an export gun for the international arms market (though it was purchased in large quantities by the German government itself). The MP 28/II includes a fire selector and a bayonet mount. Additionally, instead of the somewhat unreliable Luger P08 32-round snail magazines issued with the MP 18, this model uses conventional 20, 30 and 32-round box magazines. MP 28s are actually easier to find today than their predecessors owing to their commercial success.
