The Caliber X-Change Kit allows you to convert any P320 chambered in 9mm, .40 S&W, or .357 Sig to a full size .357 Sig. It is not compatible with .45 ACP P320's.

Note that Sig Sauer recently made an inline design change to the grip shells and slide catch levers. Watch our video below for additional information. We cannot guarantee that you will receive one or the other due to Sig using the same part numbers for the old and new style grip shells, Caliber X-Change Kits, and P250 / P320 firearms.
