   The SIG MPX is a submachine gun, developed by SIG Sauer company. It was designed in 2013. This weapon was first publicly revealed in 2014 or 2015.

   The SIG MPX is a gas operated, selective fire weapon. It has similar dimensions and weight to the popular Heckler & Koch MP5 submachine gun. Essentially it is a scaled-down SIG MCX assault rifle, chambered for a standard 9x19 mm Parabellum ammunition. It is the first submachine gun with a fully closed and rotating bolt piston system. Such system is typically associated with assault rifles and was developed for the SIG MCX assault rifle. It reduces recoil, increases accuracy and reliability of the weapon. This submachine gun is designed in the way to prevent dirt and water from entering the chamber and causing stoppages. This weapon also has some features of the Armalite AR-15 (M16) assault rifle.

   The baseline MPX submachine gun comes with a 165 mm (6.5") barrel. Though there are versions of this weapon with different barrel lengths.

   An ambidextrous fire mode selector is located over the pistol grip. It has settings for "safe", "semi-auto", and "full-auto". There are semi-automatic only versions of this weapon.

   A charging handle resembles that of the Armalite AR-15 (M16) assault rifle and is located at the back of the weapon. It does not reciprocates when the weapon is fired. The weapon can be charged with either hand.

   The SIG MPX has a last shot bolt hold open. Bolt release button is ambidextrous. These features speed up reloading of the weapon.

   This weapon is fed from 30-round capacity magazines. There are smaller magazines for civil semi-automatic only versions of this weapon.

   The SIG MPX has got a 3-position telescoping stock. There is also a version with a side-folding buttstock. Some civilian semi-automatic only models have no stock at all, or a fitted with a shoulder brace, which can act as a buttstock.

   This submachine gun comes with a full-length Picatinny-type scope rail. It comes as standard with detachable flip-up iron sights. It can also mount various red dot type sights or laser pointers. Range of effective fire is only around 50-75 meters.

   The MPX can be fitted with accessory rails on the foregrip. It allows to mount various add-on tactical accessories, such as laser pointers, flashlights and so on.

   SIG MPX-P is a semi-automatic only pistol version. It has got no buttstock and comes with a 203 mm (8") barrel. There are some other semi-automatic only versions of this submachine gun, intended for civil customers and various security services.

   SIG MPX-SBR is yet another semi-automatic only pistol version. It has a collapsible stock, similar to that of the baseline submachine gun. It comes with a 114 mm (4.5"), or 203 mm (8") barrel.
