Manufactured in many calibers, the new Px4 Storm adopts the locked-breech locking system with a rotating barrel, which has been revised and considerably improved by Beretta.The overall dimensions are significantly reduced, considering its major firepower.
The light yet resistant pistol frame has been created applying the most modern thermoplastic technology, using reinforced fiberglass technopolymer.
Modular structure, ergonomics and interchangeability of parts place the Px4 Storm among the leading pistols for personal defense as well as law-enforcement use.

Px4 User Manual

TECHNOPOLYMER FRAME.
The extensive use of reinforced  fiberglass technopolymer has allowed the development of a  light and technically advanced firearm with a modern line that is extremely attractive and ergonomic. The technopolymer is also completely resistant to corrosion and guarantees color consistency for years to come. The rounded surfaces of the pistol are truly snag-free and facilitate the insertion and the extraction of the pistol from the holster. Also the trigger guard is rounded to ensure, when firing with two hands, the correct position of the supporting hand. In front of the trigger guard, underneath the barrel, a Picatinny rail (MIL Std 1913) is located. Integral to the frame, it allows the mounting of laser devices, flash lighters or other types of accessories.

ERGONOMIC AND MODULAR GRIP.
The correct grip angle allows for instinctive aiming of the firearm, automatically providing the line of sight. The rear upper part of the grip is curved and slightly recessed to snugly accommodate and protect the shooter's hand. Both the front and the rear part of the grip boast a comfortable scaled surface that, not only has great aesthetic impact, but considerably improves grip, even in moist conditions. In addition, the pistol may be adapted for different hand sizes, even small hands, thanks to a new patented system that allows the interchangeability of the back-straps by thickness and configuration: in addition to the standard back-strap (medium), a slim back-strap is also available for small hands as well as an oversized one for large hands.

AMBIDEXTROUS AND INTERCHANGEABLE MANUAL SAFETY LEVER.
The manual safety lever is positioned on both sides of the slide for equally as easy access by right or left-handed shooters.
The model G has a hammer de-cocking lever that can be replaced with another in a low profile configuration (Stealth) to further reduce the overall dimensions of the slide.

REVERSIBLE AND INTERCHANGEABLE MAGAZINE RELEASE BUTTON.
The newly designed magazine release button can be mounted on the right side of the firearm, for use by left-handed shooters. The knurled surface improves grip. The standard button can be easily replaced in different sizes (Large and Combat), suitable for professional use.

INTERCHANGEABLE SLIDE CATCH.
The slide catch (slide stop) may be replaced by another in a low profile configuration (slim type).

REMOVABLE AND INTERCHANGEABLE TRIGGER MECHANISM.
The trigger mechanism of the Px4 Storm pistol has been designed as a unit that may be extracted without the need for special tools.
The removal of the trigger group allows an easy access to the firing mechanism for cleaning and special maintenance purposes. Qualified personnel can remove the trigger mechanism when necessary, even in the field.

ROTATING BARREL.
The model Px4 Storm pistol uses the rotating barrel locking system that provides robustness and long-life, even when using powerful calibers. Further enhanced, the system boasts extremely robust locking lugs, located at 180° in order to ensure the best distribution of locking forces when firing. The reduced friction areas between the barrel and the slide, as well as the central block, guarantee a remarkable fluency of operation and great reliability, even under poor climate conditions. In addition, the barrel features an enlarged external muzzle diameter that ensures a precise and constant barrel-to-slide coupling, shot after shot, considerably enhancing the accuracy of the pistol.
Furthermore, the reduction of the external barrel diameter for its remaining length guarantees an improved rear and forward travel of the slide during the operating cycle.

NEWLY DESIGNED SLIDE.
The sides of the slide are smoothed and snag-proofed easing the insertion and removal of the pistol from its holster. The double transversal serrations (back and rear) on the slide allow for a firm grip even in moist conditions, facilitating slide operation and safety controls.

LOW BARREL AXIS POSITION.
Thanks to the direct barrel-slide locking system and to the design of the slide itself, the barrel axis comes as close as possible to the theoretical axis of the arm that handles the pistol with the clear benefit of minimizing the muzzle jump when shooting and improving the speed of aim in fast follow-up shots.

LUMINESCENT SUPERLUMINOVA® SIGHTS,  INTERCHANGEABLE.
The high definition 3-dot sight system sports white indicators treated with Superluminova®, a special photosensitive material that makes them extremely visible even in darkness. A few minutes of exposure to light, even artificial light, are enough to ensure long lasting luminescence to the dots.The rear and front sights can be removed for replacement with other types.

SKELETONIZED HAMMER.
The weight of the hammer has been significantly reduced and features a distinctive look and high percussion speed.

AUTOMATIC FIRING PIN BLOCK SAFETY.
The Beretta Px4 Storm pistols have a blocking device that prevents forward movement of the firing pin, unless the trigger is completely pulled.
