pistol-carbine gun

Italian-made revolver with a unique design

The 9×21mm pistol cartridge (also known as the 9×21mm GP, 9×21mm IMI, 9mm IMI, 9×21mm Italian, or 9mm Italian) was designed by Jager (Loano, Italy), then adopted and commercialised by Israel Military Industries for jurisdictions where military service cartridges, like the 9×19mm Parabellum, are or were illegal for civilian purchase (i.e. France, Brazil, Mexico as well as Italy until 2021, when the 9×19mm was legalized for civilian use).
