The 7×20mm Nambu is a rimless, bottleneck handgun cartridge designed in Japan for use in the Type B or "Baby" model Nambu pistol.[1] The cartridge is a scaled-down version of the 8×22mm Nambu used in all other Nambu pistol models. It has a muzzle energy greater than that of the .25 ACP and closer to the .32 ACP.[2][3][4]
