Beretta CX4 Storm Folding Grip, 4 Position

I’ve been building online firearm retail platforms for over a decade, and in that time, I’ve seen a lot of accessories come and go. What separates the good from the forgettable isn’t just the price tag—it’s the engineering intent. The Beretta CX4 Storm Folding Grip, 4 Position, isn’t just a piece of plastic you bolt on. It’s a direct, factory-spec solution for a specific ergonomic problem. The CX4 Storm is a fantastic platform, but its factory vertical grip is a fixed, one-position affair. For shooters who run their carbine in varied positions—from tight CQB drills to supported barricade work—that limitation gets old fast. This 4-position folding grip changes the entire handling dynamic, giving you control where you need it and the ability to stow it when you don’t. It’s the kind of thoughtful upgrade that makes you appreciate the platform even more.

Miamishooterssupply is a Boise, ID-based retailer specializing in firearms parts and accessories for the DIY enthusiast and gunsmith. The Beretta CX4 Storm Folding Grip, 4 Position is a factory-original accessory that replaces the fixed vertical grip on your CX4 Storm carbine. Its key differentiator is the four-position adjustable, foldable design that enhances weapon handling and storage. This grip is in stock and ready to ship today for $41.40.

What This Grip Actually Does for Your CX4 Storm

Let’s talk function. This isn’t a universal accessory you have to force-fit. It’s a direct, drop-in replacement for the OEM vertical foregrip on your Beretta CX4 Storm. The core improvement is the hinge mechanism. You can fold it completely flat against the handguard for storage or transport—a huge benefit for anyone using a discreet bag or case. More importantly, you can deploy it and lock it into one of four distinct angles. This adjustability lets you tailor the grip angle to your specific shooting stance, arm length, and the task at hand. From a high, aggressive CQB grip to a lower, more relaxed support position for precision, you’re no longer locked into a single, factory-determined posture. The mechanism itself uses a robust locking detent, so once you set your angle, it stays put until you deliberately change it.

Features & Build Quality: A Gunsmith’s Perspective

Handling this unit, the first thing you notice is the material consistency. It’s molded from a high-density polymer that matches the texture and feel of the original CX4 Storm furniture. This matters for both aesthetics and durability. It won’t feel like a cheap add-on; it feels like part of the original weapon system. The folding hinge is the critical component. The pivot pin is steel, and the locking detent has a positive, audible click. I’ve seen aftermarket hinges that feel mushy or wear out quickly—this one is built to the tolerances you’d expect from a Beretta factory part.

Installation is straightforward for anyone comfortable with basic takedown. You remove the original vertical grip by depressing the locking tab and sliding it off the rail. This folding grip slides on in the exact same manner and locks into the same slot. There’s no gunsmithing, no modification, and no permanent alteration to your firearm. It’s a five-minute upgrade that doesn’t require any special tools. From a law enforcement or duty perspective, that’s a significant advantage; you can return the weapon to its original configuration just as easily if needed.

Pros and Cons: The Honest Breakdown

✅ Pros:

• Factory Fit & Finish: Direct OEM replacement. The polymer texture and color match the CX4 Storm handguard perfectly.
• Four-Position Adjustability: Provides real ergonomic customization for different shooting styles and scenarios.
• Positive Locking Hinge: The steel-pinned hinge and detent system is robust and holds its selected angle securely.
• Folds Flat: Dramatically improves the carbine’s profile for storage and transport in confined spaces.
• Simple Installation: No tools, no gunsmithing. A true drop-in part that takes minutes to install.
• Cost-Effective Upgrade: At this price point, it delivers a major functional improvement over the stock part.

❌ Cons:

• CX4-Specific: This grip is designed solely for the Beretta CX4 Storm. It will not fit AR-15, AK, or other platform rails. If you need a grip for a different system, see our full grips category.
• Polymer Construction: While high-quality, it is not a machined aluminum unit. For users seeking a ultra-premium metal folding grip, those options exist at a significantly higher price point.
• No Storage Compartment: Unlike some aftermarket vertical grips, this model is solid and does not include a storage tube for batteries or small parts.

Who Should (and Shouldn’t) Buy This Grip

Buy it if: You own a Beretta CX4 Storm and find the fixed vertical grip limiting. You use your carbine in multiple roles (home defense, competition, training) where grip angle matters. You need a more compact profile for storage in a vehicle or discreet bag. You value OEM-quality parts that install without modification.

Skip it if: You are looking for a grip for any firearm other than the Beretta CX4 Storm. You require a machined metal construction for extreme hard use. You specifically want a grip with an integrated storage compartment. For those needs, browse our selection of universal and platform-specific grips.
