Introduction
The Beretta PX4 Storm is a modern, polymer-framed semi-automatic pistol developed by Italian manufacturer Beretta. It is designed as a versatile service weapon for security forces and defensive shooting. The PX4 Storm is available in a range of sizes and calibers, making it suitable for a variety of uses.
History and development
In the early 2000s, Beretta wanted to offer a pistol that responded to modern trends: polymer frame, modular ergonomics and compatibility with accessories. The PX4 Storm is presented as a new platform, distinct from the metal-framed Beretta 92 series.
The development of the PX4 Storm incorporates a rotating barrel for certain versions, in order to offer a different mechanical solution to the more common tilting-barrel systems. Beretta first launched the standard-size versions, then extended the range to include compact and subcompact variants.
The PX4 Storm is offered in several common calibers, including 9×19 mm, .40 S&W and, in some variants, .45 ACP. It is used by security services, government agencies and civilian shooters in many countries.
Design and operation
The Beretta PX4 Storm is a recoil-operated semi-automatic pistol. On the standard and compact versions in 9×19 mm and .40 S&W, locking is by means of a rotating barrel. When fired, the barrel recoils for a short distance, then pivots to unlock the breech, enabling the fired holster to be extracted and ejected.
The PX4 Storm’s frame is made of polymer, with a steel slide. The safety and decocking controls, depending on the variant, are located on the slide. Typical versions offer double-action/single-action operation, with a visible external hammer.
Sights generally comprise a front sight and a notched rear sight, mounted in dovetails. On some models, these elements are interchangeable to adapt the height or type of sight.
The grip is designed to be modular. Interchangeable stock backs enable the grip size to be adapted to the shooter’s hand. The frame also features an accessory rail under the barrel, compatible with lamps or appropriate sighting devices.
On certain sub-compact variants, the locking system may differ, with a return to a tilting rather than rotating barrel principle, depending on the caliber and compactness sought.

Their main interest
The main concept of the Beretta PX4 Storm is to offer a modern service pistol combining a polymer frame, modular ergonomics and a specific locking system. The rotating barrel is designed to distribute the recoil movement and offer an alternative to the more traditional tilting barrel systems.
The presence of several calibers and different frame sizes means that the model can be adapted to a variety of contexts, such as duty carry, discreet carry or defensive sports shooting. Modular ergonomics, with interchangeable stock backs and ambidextrous or reversible controls on certain versions, are designed to facilitate handling by different users.
Main variants
The PX4 Storm range comprises several variants that differ in size, caliber and trigger configuration.
The standard version is the largest, with an approx. 102 mm barrel and high magazine capacity in 9×19 mm. It is intended primarily for security forces and service porting.
The compact version retains the general principle of the platform, but is reduced in size to facilitate porting. The length of the barrel and grip is reduced, which reduces magazine capacity compared with the standard version.
The subcompact version is even shorter, with a shortened grip and barrel. The locking system may differ from that of the standard versions, depending on the mechanical constraints associated with compactness.
Variants also differ in their trigger and safety modes, with double/single action configurations with decocking lever, or other combinations depending on the precise part number.
Comparison with other guns
Compared to Beretta pistols with metal frames, such as the 92 series, the PX4 Storm introduces a polymer frame and a more compact architecture for reduced weight. The switch to polymer is part of a general trend in contemporary service pistols.
Compared with other 9×19 mm polymer service pistols, the PX4 Storm stands out for its use of a rotating barrel on several variants, whereas many competing models use a Browning-type tilting barrel. This difference translates into specific internal kinematics.
The modularity of the grip and the presence of an accessory rail bring the PX4 Storm closer to other modern platforms. Dimensions, magazine capacity and weight place it in the same category as many contemporary service pistols.
Conclusion
The Beretta PX4 Storm is a modern, polymer-framed semi-automatic pistol designed for use as a multi-purpose service pistol. It features a rotating barrel in several versions, modular ergonomics and a range of calibers adapted to security and defense uses.
Overall, the PX4 Storm illustrates the evolution of Beretta pistols towards polymer platforms and mechanical solutions adapted to the requirements of contemporary users. Its multi-variant structure covers a wide range of needs, from the standard service version to more compact models for discreet carry.
