The UZI PRO pistol is a modernized Micro UZI semi-auto pistol based on the world famous UZI sub-machinegun, variations of which have sold in excess of 2,000,000 units worldwide. The new blow-back operated 9mm UZI PRO incorporates advanced polymers in the lower section of the receiver resulting in lighter weight and relocation of the magazine release to a more practical and familiar pistol based location. Unlike earlier UZI models, the charging handle has been moved from the top of the pistol to the left side of the receiver. This allows the addition of a full length Picatinny rail to the top of the pistol, permitting the use of any modern optics, usually red dots. An additional Picatinny rail is incorporated in the polymer lower that allows the use of lights and/or lasers to be mounted under the barrel, another location consistent with modern pistol controls. The result is a pistol, and potentially SBR, of extremely compact dimensions with carbine advantages.
