Historical profile

Development and Project Genesis

The development path of the Beretta PMX began in the early 2010s to meet the growing need to update the arsenal of the Italian security forces. Although the previous Mx4 Storm had introduced modern concepts, the company decided to further evolve the design by focusing on greater modularity and the structural strength required by special units.

The final prototype was officially presented during the Milipol exhibition in Paris in 2017, immediately attracting the attention of the Ministries of Defense and the Interior. The project aimed to replace the aging M12SD series and the PM12S2 variants, which were considered obsolete for modern operational use due to the lack of rails for optical accessories.

Architecture and Technical Features

The PMX stands out for the extensive use of high-strength polymers, combined with a cold hammer-forged special steel barrel with a length of 175 millimeters. The weapon operates with a simple yet extremely refined blowback system, which guarantees high reliability even in adverse environmental conditions or with subsonic ammunition.

Modularity is ensured by four Picatinny rails (MIL-STD-1913) allowing the installation of laser pointers, flashlights, and reflex sights, while the controls are fully ambidextrous to facilitate use for left-handed operators. Safety is guaranteed by an automatic firing pin block and a three-position selector that prevents accidental discharges in case of violent impact.

Adoption and Operational Service

Large-scale adoption officially began in 2018 with the signing of a contract for the initial supply of over five thousand units intended for the Carabinieri. Subsequently, the PMX was integrated into the equipment of the State Police and the Guardia di Finanza, finding operational use in VIP protection units and high-risk public order services.

At an international level, the weapon has also garnered interest outside Europe, being purchased in significant quantities by the Argentine Federal Police and elite Saudi police units. In counter-terrorism scenarios, the PMX has proven its effectiveness due to its precision in rapid fire at distances up to one hundred meters.

Evolution and Civilian Variants

The legacy of the PMX has extended to the civilian and sporting market with the launch of the PMX-S version, a semi-automatic variant lacking the select-fire components. This version allowed sport shooters and collectors to access a weapon with the same ergonomics and accuracy as the military model, while complying with local legislative restrictions.

The success of the platform has consolidated Beretta's position as a leader in the light defense weapons sector, confirming that the concept of a 9mm submachine gun is still fundamental despite the rise of PDWs. Today, the PMX represents the technological standard for Italian police forces, destined to remain in active service for the coming decades.
