The Sig Sauer P320 X-Series Full Size Small Grip Module (brand part no. GRIPMODXF943SMCOY) is a pistol grip module, not a shotgun accessory — this listing’s underlying category assignment does not reflect the actual product. It lets P320 owners convert their firing control unit into an X-Series Full Size configuration in Coyote polymer, fitting 9mm Luger, .40 S&W, and .357 SIG slide assemblies at the 4.70-inch size. Sig Sauer’s modular P320 system is built around swapping grip modules like this one to change size or caliber configuration without buying a new pistol, and this small-size module gives shooters with smaller hands a better fit on the Full Size platform.
