BERETTA MAGAZINE, Model “PX4 STORM FULL”, Cal. 40, 14rds, “C89132” #

Description

The Beretta PX4 Storm in .40 S&W is a proven sidearm for American shooters who value reliability and controlled power. Whether you are a law enforcement officer looking for a duty-ready backup, a competitive shooter seeking a durable platform for USPSA Limited division, or a responsible citizen preparing for home defense, this full-size pistol delivers consistent performance. Beretta’s engineering pedigree, combined with the .40 S&W cartridge’s balance of stopping power and magazine capacity, makes this model a practical choice for those who need a firearm that works without excuses.

What This Product Is and Who It’s For

The Beretta PX4 Storm Full is a semi-automatic, striker-fired pistol chambered in .40 S&W, designed for shooters who prefer a larger frame for better recoil management and sight radius. This is not a compact or subcompact model; it is the full-size variant intended for range training, home defense, and duty use. It appeals to target shooters who want a consistent trigger pull and low bore axis for fast follow-up shots, as well as collectors who appreciate Beretta’s rotating barrel system—a unique design that reduces felt recoil and improves accuracy. For those who hunt small game or varmints with a handgun, the PX4’s 4-inch barrel offers sufficient velocity for ethical shots at moderate distances.

Feature Deep-Dive

The Beretta PX4 Storm Full uses a rotating barrel system, a departure from the traditional tilting barrel found on most modern pistols. This design locks the barrel into the slide during firing, then rotates it slightly to unlock, reducing the felt recoil and muzzle rise. For a .40 S&W cartridge, which produces more snap than 9mm, this mechanism helps keep the sight picture flatter during rapid fire. Shooters transitioning from a 9mm will find the .40 PX4 manageable, with less fatigue over a long range session compared to fixed-barrel designs.

The frame incorporates Beretta’s “Pin-Lock” system, which secures the trigger group and locking block with steel pins rather than polymer retention. This adds durability and simplifies disassembly for cleaning. The replaceable grip backstraps and side panels allow you to adjust the circumference and texture to match your hand size—a useful feature for shooters who wear gloves or prefer a more aggressive texture. The trigger guard is undercut, letting you place your support hand higher for better control.

Slide serrations are cut front and rear, giving you multiple purchase points for press checks or clearing malfunctions. The Bruniton finish on the slide is a salt bath nitrocarburizing process that resists corrosion and wear, even in humid conditions or after exposure to sweat. The barrel is cold-hammer-forged from stainless steel, which provides consistent accuracy and longevity. The feed ramp is polished from the factory to reduce the chance of failures with hollow-point ammunition, though you should always test defensive loads for reliable feeding.

The DA/SA trigger system offers a longer, heavier first pull (approximately 12 pounds) followed by lighter single-action pulls (around 5.5 pounds). This gives you an additional layer of safety for holstering or home storage, as the first pull requires deliberate effort. The decocking lever is ambidextrous, allowing left-handed shooters to lower the hammer safely without lowering the trigger. The trigger itself has a smooth face and a short reset, which aids in controlled pairs and rapid strings.

Magazine release is reversible and sits flush with the frame to prevent accidental drops. The 14-round steel magazines are double-stack with a polymer basepad, and they drop free when the release is pressed. The magazine well is slightly beveled to aid in reloads under stress. The slide stop is low-profile but easy to reach without shifting your grip, and it engages positively on the last round. The extractor is external and claw-type, providing visual confirmation of chamber status.

The PX4 Storm’s low bore axis (approximately 0.5 inches above the hand) reduces torque during recoil, allowing faster follow-up shots. The grip angle is 22 degrees, similar to the 1911 platform, which helps shooters who are accustomed to that grip find a natural point of aim. The trigger guard is squared off at the front, giving you a place to index your support hand finger for consistent grip placement. The overall fit and finish are consistent with Beretta’s Italian manufacturing standards, with tight slide-to-frame fit and minimal play.

Ideal Use Cases

• Home Defense: The full-size frame and 14-round capacity provide a stable platform for low-light or high-stress scenarios. The rotating barrel helps manage recoil, and the DA first pull reduces the chance of an accidental discharge if startled.
• Range Training: The PX4’s consistent trigger and low bore axis make it a good choice for shooters working on fundamentals. The .40 S&W cartridge offers more recoil than 9mm, helping you practice recoil management without moving to a magnum round.
• Competition: Suitable for USPSA Limited or IDPA SSP divisions. The capacity is competitive, and the rotating barrel system can give an edge in accuracy. The three-dot sights are adequate for most matches, though you can swap them for fiber-optic or night sights.
• Duty/Backup: Law enforcement or security personnel may choose this as an off-duty or backup gun. The .40 S&W is still widely used by agencies, and the PX4’s reliability in adverse conditions is well-documented.
• Hunting: For small game or pest control at close ranges (under 25 yards), the .40 S&W with appropriate ammunition (such as 180-grain hardcast) offers sufficient energy. The 4-inch barrel provides adequate velocity for ethical shots on raccoons, coyotes, or feral hogs.

Compatibility Notes

• Ammunition: This pistol is designed for .40 S&W ammunition meeting SAAMI specifications. It will function with 155-grain, 165-grain, and 180-grain loads, both FMJ and JHP. Avoid +P or +P+ ammunition, as it may accelerate wear on the rotating barrel system. For best results, test your chosen defensive load for reliable feeding and ejection.
• Holsters: The PX4 Storm Full fits most holsters designed for the full-size PX4 platform. Popular options include Kydex holsters from Safariland, Blade-Tech, and Alien Gear, as well as leather holsters from Galco or DeSantis. Ensure the holster is molded for the .40 model, as the slide profile is identical to the 9mm version.
• Magazines: Use factory Beretta 14-round magazines for reliable feeding. Aftermarket magazines from Mec-Gar (which supplies OEM for Beretta) are also compatible. Do not use 9mm PX4 magazines, as the feed lips and follower geometry differ.
• Accessories: The PX4 has an integrated accessory rail (Picatinny-style) for mounting lights or lasers. Streamlight TLR-1, SureFire X300, and Olight PL-2 are common fits. The slide can be milled for red dot sights by a qualified gunsmith, though Beretta does not offer a factory optic-ready version for the .40 model. Grip inserts are available in small, medium, and large sizes from Beretta or third-party vendors like Hogue.
• Parts: Trigger springs, recoil springs, and extractors are available from Beretta USA. The rotating barrel cam and locking block are specific to the PX4 and should be replaced by a certified armorer if worn.

Frequently Asked Questions
