The original design of the Nambu pistol series could be attributed to the Japanese General Kijiro Nambu in the early 1900s. The Type 14 was conceived in 1925, an improvement over the earlier designs of the pistol, which had previously existed as the Type A and Type B Nambu pistols. The Type 14 was a standard issue in the Imperial Japanese Army during World War II and it was widely used in the Japanese campaigns in Southeast Asia, including Singapore.
