Beretta unveils PMX 9 mm sub-machine gun

19 November 2017

Beretta is set to unveil its new PMX 9 mm sub-machine gun (SMG) at the Milipol 2017 exhibition in Paris from 21-24 November.

The PMX will replace the company’s venerable Model 12 series of 9 mm SMG developed in the 1950s and its subsequent successor models, which are no longer in production.Beretta's new PMX 9 mm sub-machine gun is around 1 kg lighter than the company's venerable Model 12 series weapon.

Designed with improved reliability, accuracy and safety in mind, the PMX is a blowback-operated weapon that adopts a closed-bolt design and can be stripped on the field without tools. Although the new weapon’s tubular frame shares some aesthetical similarities with its predecessor, it is fully ambidextrous with the exception of the hold-open catch, which is located on the left side.

The new weapon measures 640 mm long with its stock fully extended, this being reduced to 418 mm when folded. The frame is constructed from polymer to reduce weight and is fitted with a full-length Picatinny rail on the 12 o’clock position and three shorter rails at 3, 6 and 9 o’ clock positions. The top rail is typically used to mount foldable sights with the front and rear sights compensating for elevation and windage respectively.

It is fitted with a 175 mm long cold-hammer forged barrel, with a six-groove, right hand, one turn in 254 mm rifling. The 9x19 mm calibre NATO 115 grain ball cartridge can achieve a claimed muzzle velocity of approximately 400 m/s.

A suppressor is presently being developed by Beretta in collaboration with an unspecified partner.

The three-position firing mode selector is designed to enable the operator to rapidly come into action with a narrow range of movement required for the switch to be moved from ‘S’ (safe) to ‘I’ (semi-automatic) fire. However, the transition to ‘R’ (full automatic) requires a swing of over 90°, a feature aimed at reducing the likelihood of inadvertent selection.
