Choroszmanów submachine gun

Choroszmanów submachine gun (Pistolet maszynowy Choroszmanów) was a Polish gun created by Grzegorz Choroszmanów during German occupation of Poland between the years of 1943-1944. Choroszmanów manufactured this weapon with his sons in the area of Podlesie. It was used by Polish partisans in the Tadeusz Kościuszko unit, which men fought in and around Podlesie.

The design was based roughly on the Russian PPD-40. It was a simple, sturdy and capable design that was easy and inexpensive to produce. This design allowed Polish partisans to significantly increase the ferocity of raids and guerrilla strikes against the occupiers. Only 22 copies of this gun were created between 1943-1944 due to lack of resources and the prevalence of the Polish Błyskawica submachine gun.
