Type 100 submachine gun

Small Arms And Sidearms

The Type 100 submachine gun was a Japanese submachine gun designed by Kijiro Nambu and manufactured at the Nagoya Arsenal, the only submachine gun produced by Japan in significant quantity during the Second World War. Chambered for the 8x22mm Nambu cartridge, it was designed in 1939 and entered service in 1942, with roughly 8,500 to 10,000 total units built between 1942 and 1945 across an early Type 100/40 model and a later, simplified Type 100/44 model. It was issued to both the Imperial Japanese Army and the Imperial Japanese Navy.

FAQs

Why was the Type 100 simplified in 1944?

Australian War Memorial states: Late production models introduced in 1944 were greatly simplified in order to hasten production at a time when Japan was being pushed into retreat across the Pacific theatre and demand for submachine guns was at an all time high. The 1944 variant was slightly longer, and featured simple iron sights. Corners were cut in production, leaving many Type 100s with roughly finished stocks and poorly welded parts.

What was unusual about the design of the Type 100?

Australian War Memorial states: The Type 100 was a well made gun, albeit with several strange features, including a complicated ammunition feed device that, for safety purposes, ensured that a round was completely chambered before firing, a complex system compounded by the curious bottle shaped round the Type 100 used. A bayonet lug was fixed under the barrel. Despite its shortcomings and complexities, the Type 100 featured sophisticated sights and a high quality chrome plated barrel to aid cleaning and reduce wear.
