Pistol frame USW-320
The new accessory is a pistol frame equipped with a swiveling stock. The USW-320 is compatible with the SIG Sauer P320 pistol and its military version M17. In addition, the B&T frame is adapted for both standard and large-capacity magazines.
The length of the USW-320 frame with unfolded stock is 36 cm, and its weight is 188 g. With the stock folded, the frame thickness will be only 43 mm. But even considering the small thickness, the use of the USW-320 will make most of the standard holsters for the SIG Sauer P320 unsuitable for carrying a pistol. Therefore, B&T indicates that they intend to release a series of special holsters that allow the SIG Sauer P320 to be carried when using a frame with a stock.
Due to its modular design, the SIG Sauer P320 pistol frame is not a number part and in many countries can be sold as an accessory that does not require a license or special permission. The USW-320 is compatible with full-size and short-cut models of the SIG Sauer P320 pistol and will appear in retail sales this summer, then the price of the accessory will be announced.
