Specifications
The Beretta CX4 Storm’s synthetic stock construction keeps the weight under 6 pounds while maintaining durability. You’ll find the 16.7-inch barrel provides excellent accuracy across all four available chamberings: 9x19mm, .40 S&W, 9x21mm, and previously the .45 ACP. The carbine’s capacity varies by caliber choice and accepts standard Beretta pistol magazines for seamless compatibility.

Weight
Weighing in at under 6 pounds, Beretta’s CX4 Storm achieves its lightweight profile through advanced polymer construction and a synthetic stock design. You’ll find the carbine’s maneuverable nature enhances handling during extended shooting sessions.
The polymer construction and lightweight design work together to help manage the linear impulse recoil, making the CX4 Storm comfortable to operate in various shooting scenarios.
Barrel Length
Standard CX4 Storm models feature a 16.7-inch barrel length, meeting civilian market requirements while optimizing ballistic performance for pistol-caliber ammunition.
The fixed barrel design complements the Picatinny rail system, iron sights, and charging handle configuration for both short range and long range engagements.
While specialized 12-inch variants exist for law enforcement, you’ll find the standard barrel integrates seamlessly with the overall length.
Material Made Out Of
Primarily constructed from high-impact polymer materials, Beretta’s CX4 Storm incorporates strategic metal components for its internal operating system while maintaining a lightweight profile.
Despite what you’ve might’ve heard about polymer guns, the Storm’s durability shines through – I’ve seen these carbines survive concrete drops without issue. The design features an ambidextrous pistol grip and operating controls accessible from either side, with Picatinny rails molded into the polymer frame.
Chambered In
The Beretta CX4 Storm offers a versatile array of chambering options across multiple calibers. You’ll find the rifle available in 9x19mm, 9x21mm, .40 S&W, and .45 ACP configurations.
The 9x19mm variant delivers 1,325 fps muzzle velocity, while the .40 S&W generates 1,198 fps. For maximum stopping power, the .45 ACP model produces 1,026 fps at the muzzle.
Capacity
Depending on your chosen caliber, magazine capacity for the CX4 Storm ranges from 8 to 30 rounds. You’ll find the .45 ACP variant accepts 8-round Beretta Cougar magazines, while models chambered in 9mm and .40 S&W can utilize standard Beretta 92FS magazines.
The rifle’s versatile design also accommodates PX4 Storm pistol magazines, giving you flexibility in choosing your preferred magazine configuration.
Trigger Pull
Measuring in at approximately 9 pounds, trigger pull characteristics represent a notable design consideration when operating the CX4 Storm. You’ll experience a heavy, gritty trigger pull with a clean break, followed by a long reset that demands conscious effort between shots.
While aftermarket trigger upgrades are available to enhance performance, installing them may void your warranty. The stiff trigger mechanics can affect shooting accuracy.
Safety?
Several safety mechanisms define the CX4 Storm’s core specifications, including a cross-block safety that’s heavily fenced in on newer production models. While this design enhances protection against accidental disengagement, you’ll find the safety operation somewhat challenging to access.
The rifle’s ambidextrous features extend to the fire selector, allowing both right and left-handed shooters to manipulate safety controls with equal effectiveness.
Action
The Beretta CX4 Storm operates on a straight blowback action system, delivering a maximum cyclic rate of 1,000 rounds per minute.
You’ll find this simple yet reliable mechanism pairs effectively with multiple caliber options, including 9x19mm, 9x21mm, .40 S&W, and .45 ACP. The blowback action helps achieve muzzle velocities of up to 390 m/s, maintaining accuracy through an effective range of 200 meters.
Optic Ready?
Built for versatility, the CX4 Storm comes factory-equipped with an integrated Picatinny rail system mounted along its top receiver, accommodating a wide range of optical sights and accessories.
You’ll find extensive optic customization options through the tri-rail adapter system, allowing you to mount tactical lights and lasers. The rifle’s ambidextrous design ensures unobstructed sight picture regardless of your shooting hand, while maintaining compatibility with various Beretta pistol magazines.
Picatinny Rail?
Standard MIL-STD-1913 Picatinny rail integration adorns the CX4 Storm’s top receiver, providing a 16.75-inch mounting surface for tactical optics and accessories.
The Modular Design of the rail system lets you customize your sighting options with precision. You’ll find seamless compatibility with a wide range of optics, from red dot sights to traditional scopes. This standardized interface ensures you can configure your CX4 Storm to match your specific shooting requirements.
Review
The CX4 Storm’s excellent ergonomics and pistol-like controls make it a favorite among law enforcement agencies and civilian shooters, though you’ll need to overcome the limited adjustability of the polymer sights if you’re not mounting optics.
You’ll find the 9mm variant offers the best balance of controllability and magazine capacity, while being notably more reliable than the .45 ACP version which can be punchy for smaller-framed shooters.
The carbine’s blowback operation and robust polymer construction deliver consistent reliability for patrol and home-defense scenarios, with military and law enforcement units in Italy and the United States being primary adopters.
