Beretta · Carbine · In Production · 2003
Also known as: Cx4, Cx4 Storm
Overview
The Beretta Cx4 Storm is a pistol-caliber carbine introduced in 2003, designed by Beretta as a sporting, personal-defense, and law-enforcement companion to the Px4 Storm pistol. It uses a straight blowback action and accepts magazines from the Beretta 92/96, 8000 Cougar, and Px4 Storm pistol families through swappable magazine wells. The Cx4 features fully ambidextrous controls - fire selector, charging handle, ejection port, and magazine release can all be reversed - and is offered in 9x19mm Parabellum, 9x21mm IMI, .40 S&W, and .45 ACP.

Notes
The fully-automatic submachine gun derivative is sold as the Beretta Mx4 Storm with a 12-inch (305 mm) barrel for military and police use. The Cx4 was paired with the Px4 Storm pistol for matching ergonomics and shared magazines.
Background
Designed alongside the Px4 Storm pistol as a matched system, the Cx4 was Beretta's pitch that a household could share magazines between the bedside pistol and the home-defense carbine - a marketing idea aimed squarely at American shooters who already owned a Beretta 92.
