The Beretta Storm family was launched in 2003 with the Cx4 pistol-caliber carbine.
This innovative product is accurate, softshooting and easy to accessorize. Today's shooter demands a gun that can accept a large assortment of accessories, and the Cx4 meets the challenge.

A retractable Picatinny rail extends from the fore-end for mounting tactical lights. Picatinny rails can be mounted on either side (one side rail included) and bottom of  the fore-end for lasers or forward grips. A full length aluminum top rail is included for mounting your optics.
This light and compact gun also features a unique patented design that allows the user to reverse ejection and extraction with no special tools or additional parts. Combined with the reversible safety and magazine buttons, the Cx4 is the ideal solution for lefthanded shooters. Length-of-pull can be adjusted with the addition and removal of ½" spacers (one included).

The Cx4 accepts the Beretta family of pistol magazines in various capacities. From the 20 round magazines of the 92 and Px4 pistols, to the 17 round magazines of the .40 caliber Px4, there is a Cx4 configuration to complement every Beretta pistol.
