New Beretta Mx4 Storm Submachine Gun

The Beretta Mx4 Storm is a new submachine gun version of the Beretta Cx4 Storm semi-automatic carbine. The Mx4 has been designed for the Indian Ministry of Home Affairs who should be receiving their first shipment in the next 12 months.

The gun is chambered in 9x19mm NATO. It features a 12″ barrel and has a total length of 25″. It weights 6.28 lbs (including magazine). I am guessing that the magazine pictured is Beretta’s 30 round magazine. I could be wrong, but it looks to me like the barrel is threaded for a suppressor and a thread protector has been screwed on.

If I owned a Beretta Cx4, the first thing I would want to do it chop the barrel down to 12″ (I currently own a 12″-barreled carbine and love it).

    i think the mx4 is a great weapon. accurate, light, and if you use the armor piercing sabot round from vbr belgium, it could be a very effective gun.

    I've had a 9mm CX4 for a few years now. It's mounted with a Zeiss ZPoint red dot sight, an Insight Tech light/laser, a SureFire 6P light, and two spare mags on the stock. I use a single point tactical sling. While it's primary role is home defense (I live in the remote countryside), I've also used it for night armadillo hunting. It's very accurate, and most deadly on 'dillos. I'm up to 16 of the pests so far. This night hunting has given me some valuable practice at using the carbine in low light conditions, and comes as close to tactical use as possible without someone who can shoot back. I consider the CX4 to be an excellent tactical arm.

    My only complaint about it is the lack of a "fence" around the magazine release button. I have twice accidently ejected a loaded magazine by having the button hit a part of my "kit" on or in a tactical vest.
