The Sig Sauer P320 X-Series Full Size Small Grip Module (brand part no. GRIPMODXF943SMBLK) converts a P320 firing control unit into a Full Size X-Series pistol chambered in 9mm, .357 SIG, or .40 Auto, built for shooters who want a more compact grip circumference on the Full Size platform. Sig Sauer designed the P320 around exactly this kind of modular swap, letting one certified firing control unit serve multiple grip sizes without buying an entirely new pistol. This small-size module is finished in black polymer and requires the matching slide and barrel to complete the conversion.
