BERETTA PX4 Storm semi-automatic pistol

The Beretta PX4 Storm is a full-size semi-automatic pistol developed to combine reliability, durability, ergonomics, and control in a modern platform. One of its most distinctive elements is the exclusive rotating barrel locking system, designed to leverage the rotational movement during the firing cycle and contribute to a smooth and controllable recoil sensation.

Its short recoil operation is paired with a single and double action (SA/DA) trigger mechanism and an external hammer. The frame is made of fiberglass-reinforced technopolymer, while the steel slide features Beretta's signature resistant Bruniton® finish.

Ergonomics play a fundamental role in the PX4 Storm. Its grip allows for the use of interchangeable backstraps to accommodate different hand sizes, while the controls and overall geometry are designed to provide intuitive handling. In 9×19mm caliber, it offers a capacity of 17 cartridges, a 102mm barrel, and balanced full-size dimensions.

Key features

Rotating barrel system

The main technical feature of the PX4 Storm is its geometric locking system via rotating barrel. During the operating cycle, the barrel performs a rotational movement that is part of the assembly's locking and unlocking process.

This design clearly differentiates the PX4 from other semi-automatic pistols with conventional tilting barrel systems.

Short recoil operation

It uses a semi-automatic short recoil system, combined with the rotating locking mechanism characteristic of the PX4 platform.

SA/DA action

The single and double action (SA/DA) mechanism allows the first shot to be fired in double action and subsequent shots in single action after the slide movement.

External hammer

The PX4 Storm uses an external hammer, allowing for visual inspection of its position and forming part of the pistol's traditional SA/DA system.

Technopolymer frame

The frame is manufactured in fiberglass-reinforced technopolymer, providing structural strength and helping to keep the overall weight down.

Slide with Bruniton® finish

The slide is made of steel and features a Bruniton® surface finish, developed to provide resistance against wear and corrosion.

Chrome-lined barrel

The steel barrel features a blued exterior finish and a chrome-lined interior, increasing its durability and facilitating maintenance.

102 mm barrel

In 9×19mm caliber, it is equipped with a 102 mm barrel, equivalent to approximately 4 inches, with six-groove right-hand rifling.

17-cartridge capacity

The 9×19mm caliber configuration uses a double-stack magazine with a capacity of 17 cartridges.

Adaptable grip

Grip ergonomics can be modified via interchangeable backstraps, allowing the volume to be adapted to different hand sizes.

Removable sights

The front sight and rear sight are mounted on the slide and are removable, allowing them to be replaced with other compatible systems.

Accessory rail

The frame incorporates a front rail that allows for the installation of accessories compatible with the platform.
