History
Italy's domestic pistol cartridge, legally allowed in civilian use where 9mm Parabellum is restricted to military. Developed in 1990 with dimensions that prevent chambering in standard 9mm Luger pistols, enabling Italian civilians to own semi-automatic pistols without competing with military cartridge specifications.
