The CX4 Storm is a pistol-caliber carbine aimed at the sporting, personal defense and law enforcement markets. Seven different models accept full-size Beretta magazines from the 92/96, Cougar, and Px4 series pistols in 9x21 IMI (its original caliber), 9x19mm Parabellum, .40 S&W and .45 ACP.
The Beretta Cx4 Storm is the civilian version of the Beretta Mx4 Storm.
The Cx4 Storm was developed to be used in conjunction with Beretta semi-automatic pistols. For example, the magazines for the Beretta 92FS chambered in 9mm can be used in the Cx4 (also chambered in 9mm). This aids in a smaller loadout – no longer needing to carry separate magazines for the rifle and handgun – and adds redundancy, allowing a person to carry more ammunition without adding weight.
