The Experimental Submachine Gun(試製自動短銃,Shisei jidō-tanjū) was a submachine gun of Japanese origin, manufactured by Tokyo Arsenal. [1] The Imperial Japanese Army developed the Model 1927, which was fed from a drum magazine. It was ordered from Tokyo Arsenal and tested by the army. However, it was inferior to submachine guns such as the MP 18, and broke during the test. In 1930, a second trial was conducted, and the gun was again by rejected by the army. Model 1 was made in 1936 and Model 2 was made in 1937. Model 2 was at first 6.5 mm caliber, but was later revised to 8 mm.

Imperial Japanese Army Official ground-based armed force of the Empire of Japan, from 1868 to 1945

The Imperial Japanese Army was the official ground-based armed force of the Empire of Japan from 1868 to 1945. It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the navy. Later an Inspectorate General of Aviation became the third agency with oversight of the army. During wartime or national emergencies, the nominal command functions of the emperor would be centralized in an Imperial General Headquarters (IGHQ), an ad-hoc body consisting of the chief and vice chief of the Army General Staff, the Minister of the Army, the chief and vice chief of the Naval General Staff, the Inspector General of Aviation, and the Inspector General of Military Training.

MP 18 submachine gun

The MP 18 manufactured by Theodor Bergmann Abteilung Waffenbau was the first submachine gun used in combat. It was introduced into service in 1918 by the German Army during World War I as the primary weapon of the Sturmtruppen, assault groups specialized in trench combat. Although MP 18 production ended in the 1920s, its design formed the basis of most submachine guns manufactured between 1920 and 1960.
