The UZI PRO SB features a side-folding Stabilizing Brace, produced for IWI US by SB Tactical LLC, designers and manufacturers of the original SB15 and SB47 Pistol Stabilizing Braces. 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 brace‚s 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. In all other respects, the UZI PRO UPP9SB is identical to the UPP9S, 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 result
