Can you shoot a 9mm out of a 380?

Answer 1

The .380 ACP is a 9mm cartridge - 9x17mm. That is the ONLY cartridge which can be fired from a .380 pistol, and the 9x18mm Makarov, 9x19mm Parabellum/Luger, 9x21, 9x23, 9x25, etc. cartridges are NOT compatible. The Makarov cartridge actually uses a 9.3mm projectile, which is too large for the .380, and the 9x19 cartridge uses too long a case, meaning you won't get proper headspacing in the chamber, and it's designed for a locked breech pistol, generating too much pressure to be safely used in an unlocked breech pistol such as a .380. Do not attempt to use any ammunition other than what your firearm is intended to shoot.
