Beretta CX4 Storm

About the CX4 Storm

Beretta designed the CX4 Storm as a companion to their PX4 Storm pistol — sharing the same rotary-breech operating system, the same magazines, and similar ergonomic controls. The concept is a matched pistol/carbine pair where a shooter can carry a PX4 or 92 series pistol and a CX4 carbine that uses the same magazines. The CX4 also accepts Beretta 92 series magazines with the appropriate magazine well insert, making it compatible with one of the most common double-stack 9mm magazines in circulation.

Key Features

Fully ambidextrous controls — The CX4 Storm's charging handle, magazine release, and safety are fully reversible for left-handed shooters — a genuine differentiator in the PCC market where most competitors are right-hand-dominant designs.

Magazine compatibility — Accepts Beretta PX4 and 92 series magazines (with insert). The CX4 paired with a Beretta 92FS or M9 gives you a pistol and carbine that run the same 15 or 17-round magazines — a practical advantage for training and home defense.

Picatinny rail — Top and bottom Picatinny rails for optics, lights, and accessories. A red dot transforms the CX4 into a precise close-to-medium range carbine.

Adjustable stock — Length of pull adjusts to fit different shooters — useful for families where multiple people may use the same carbine.

Best Uses

The CX4 Storm is at its best as a home defense carbine for Beretta pistol owners — the magazine sharing makes it a practical companion to a 92FS or PX4. It's also an excellent first rifle for new shooters: 9mm recoil is minimal, the manual of arms is simple, and the ergonomics are accessible. For competition shooters, the CX4 is legal in PCC divisions of USPSA and similar formats.

CX4 Storm vs. Other PCCs

The CX4 Storm competes with the Ruger PC Carbine, Kel-Tec Sub-2000, and Hi-Point Carbine in the pistol caliber carbine market. The CX4's advantages are Beretta's build quality, full ambidexterity, and magazine compatibility with the 92 series. The Ruger PC Carbine is more versatile in magazine compatibility (accepts Ruger and Glock magazines). The Sub-2000 folds in half for storage. The CX4 is the premium option in the segment with Beretta's reliability track record behind it.

FAQ

What magazines does the Beretta CX4 Storm use?
The CX4 Storm accepts Beretta PX4 Storm magazines natively. With the appropriate magazine well insert (included), it also accepts Beretta 92 series magazines — 15 or 17-round double-stack 9mm mags.

What caliber is the Beretta CX4 Storm?
The CX4 Storm is primarily available in 9mm. Earlier production also included .40 S&W and .45 ACP variants, though 9mm is the current production configuration.

Is the Beretta CX4 Storm good for home defense?
Yes — the 9mm carbine format offers better accuracy at distance than a pistol, reduced recoil compared to a rifle, and the magazine compatibility with Beretta 92 and PX4 pistols makes it a practical matched pair for home defense.

Is the CX4 Storm still in production?
The CX4 Storm has been in production since 2003. Beretta continues to produce it, though availability can vary. Check current inventory for in-stock configurations.

How does the CX4 Storm compare to the Ruger PC Carbine?
The Ruger PC Carbine accepts Glock and Ruger magazines and has a takedown design for easy transport. The CX4 Storm pairs specifically with Beretta 92 and PX4 magazines and offers fully ambidextrous controls. Both are quality PCCs — the choice comes down to which pistol ecosystem you're already in.
