Description
The Sig Sauer P320 X-Series Grip Module is a factory black polymer grip frame assembly designed to convert your P320 Fire Control Unit into an X-Series Full Size configuration chambered in 9mm Luger, .40 S&W, or .357 SIG.
This small size module fits the 4.70″ Full Size P320 slide and accepts the standard P320 magazine family. The X-Series grip features an enhanced magwell design and is weight compatible, allowing installation of an optional steel weight to bring the assembled pistol up to competition-legal heft.
Installation is straightforward: slide your P320 Fire Control Unit into this grip module and pair it with a compatible slide, barrel, and magazine to build or upgrade your P320. This is a genuine Sig Sauer OEM part manufactured to factory specifications for reliable fit, function, and finish.
