The Nambu pistol was a semi-automatic pistol used by the Imperial Japanese Army and Navy during the First and Second World Wars. The pistol had two variations, the Type A (also called the Type 4), and the Type 14.The Nambu was never officially adopted by the Japanese military as officers were expected to purchase their own pistols. The pistol was made available to officers at the Officers Union, where most officers purchased equipment. It was the most common side arm of the Japanese armed forces, but many officers could, and did purchase more reliable western sidearms.Most of the pistols were produced by the Tokyo Arsenal with a smaller number manufactured by the Tokyo Gas and Electric company. Large scale production began in 1906 and continued until it was replaced by the Type 14 in 1925. Production of Type 14s lasted until the end of World War II in 1945. Total production numbers are estimated at just under 200,000 for all variants. Most detailed production records were destroyed in the war.The pistol was removed from service when Japan was disarmed after World War II. Many were taken home by Allied Servicemen after World War II. Many have found their way into collectors markets in America and western Europe.
