The 9mm Japanese revolver was a cartridge similar to the .38 S&W. These cartridges are not interchangeable. The rim of the 9mm round is much thinner and the chamber pressure is lower than most .38 S&W loads. The cartridge saw action with the Type 26 revolver in Russo-Japanese War, World War I, and World War II.
