The UZI PRO SB features a side-folding Stabilizing Brace, produced for IWI US by SB Tactical LLC. Originally designed as a means for persons with limited mobility to operate and fire the AR-15 pistol, the custom adaptation of the Stabilizing Brace to the UZI PRO SB takes the application of large frame pistol control and stabilization to a new level. With the IWI braces unique sidefolding feature, the UZI PRO SB can be fired with or without the brace extended depending on the shooters need. With the brace in the folded position, storage space required in your safe or range bag is minimized. 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 traditional 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 optical device that utilizes a Picatinny rail clamp mount. An additional Picatinny rail is incorporated in the polymer lower that allows the use of lights and/or lasers to be mounted directly under the barrel.
