The Uzi Pro, an improved variant of the Micro Uzi, was launched in 2010 by Israel Weapon Industries Ltd. (I.W.I.), formerly the "magen" ("small arms") division of Israel Military Industries. The Uzi Pro is a blowback-operated, select-fire, closed-bolt submachine gun with a large lower portion, comprising grip and handguard, entirely made of polymer to reduce weight; the grip section was redesigned to allow two-handed operation and facilitate control in full-automatic fire with such a small-sized firearm. The Uzi Pro features four Picatinny rails, two at the sides of the barrel, which can be removed, one below the barrel for the addition of forgrips and one on the top for optics. The under barrel rail is often shown with a specialised foregrip which attaches to the pistol grip to form a hand guard. In addition, the cocking handle has been moved to the left side. The new weapon weighs 2.32 kg and has a length of 529 mm with an extended stock, and 30 cm while collapsed. It has been purchased by the IDF in limited numbers for evaluation and it is yet to be decided whether or not to order additional units for all of its special forces.
