The Nambu was the standard issue sidearm of The Imperial Japanese Armed Forces from 1906 to 1945. During it's production run. It featured 5 variants with 400,000 Models manufactured. The Type 14 was the most produced. Utilizing an 8mm jacket round, The Nambu was 2-pounds in weight and 5-inches long. It used a 7 round, straight clip magazine. The Type 14 had a 100 yard maximum effective range. Officers were issued a 7mm version that was essentially the same, and still known as a Type 14 Pistol. These were slightly smaller. The Nambu was designed after Nazi Germany's standard sidearm, The Luger. Soldiers jokingly called it "The Grandpa", due to it's 30-year production run, virtually unchanged.
