Beretta's Cx4 Storm redefines the pistol-caliber carbine, with racy and radical lines from the masters of industrial design at Giugiaro. Form follows function in a symphony of smooth, sweeping curves made possible by the use of modern high-strength techno polymers. Beretta's use of cutting-edge materials also keeps weight down to just 53/4 lbs., making the Cx4 a pleasure to carry, whether in the field or on duty. Five different models accept full-size Beretta magazines from the 92/96 and Cougar series pistols in 9mm, .40 S&W and .45 Auto, including large-capacity restricted and pre-ban styles. The cold hammer-forged 16.6-inch barrel is chrome-lined for long life and corrosion resistance with any ammo.
