The KIS machine pistol,Another weapon created by the Polish Resistance during World War II, the KIS was a submachine gun or machine pistol that was modeled after the British Sten gun.  Like the Sten, the KIS was a fully automatic weapon that fired using an open bolt and was fed from a detachable magazine at the left hand side of the receiver.  The KIS, however, had some modifications that differed from the original design.  Instead of a shrouded barrel the KIS used a longer 6 inch tapered barrel.  The KIS also lacked a buttstock, instead using a pistol grip. The name KIS is derived from the initials of three men who designed and built the weapon.  The were produced around the Holy Cross Mountains region of southern Poland.  Essentially they were manufactured by cottage industry, with people producing parts in small workshops, attics, and basements.  Around 37 or 38 were produced altogether between 1943 and 1944.  They were all issued to the resistance group under the command of Jan Piwnik, who harassed the German Army throughout 1943 and 1944.  He was killed in action in June of 1944. -- source link
