USW-320 – DETAILED INFORMATION
The USW-320 Upgrade Chassis is a Swiss designed, engineered and produced polymer lower for the SIG
Sauer P320 and M17 that, once converted, combines the size of a normal duty pistol but extends its range,
accuracy and effectiveness to that of a 9 mm police carbine. It is ideal for general Police work but also for
Airport Police, Railway Police, Customs Service, Harbor Security and Air Marshals. Anywhere, where the
necessity of a shot at longer distances may occur.
The features of the USW-320 will enable the shooter to produce very tight shot groups at 25 meters / 27
yards and to place fi rst round incapacitating hits at distances beyond 50 meters / 55 yards. This is possible
even under the stress of a life-threatening confrontation. The purpose designed holster with various types of
attachments (belt/thigh/MOLLE) will provide safe and reliable portage of the weapon during all missions
and enable the operator to draw and fi re the weapon as fast as any standard duty pistol. Unfolding the stock
during the draw process adds just minimal time.
The USW-320 is the perfect upgrade for the P320 and the M17.
