The SIG Sauer P320 X-Series Large Grip Module (SIG part no. GRIPMODXF943LGCOY) lets P320 owners convert their existing fire control unit into a full-size X-Series build finished in Coyote polymer. Drop your 9mm, .357 SIG, or .40 S&W fire control unit into this module and pair it with the matching slide and barrel to complete the conversion. SIG built this module in the large frame size to fit the full-size X-Series footprint (4.70-inch slide length). Shooters expanding a single P320 fire control unit into multiple builds pick this module to add an X-Series configuration to their existing setup.
