Sig Sauer’s Caliber X-Change Conversion Kit allows shooters to convert any P320 chambered in 9mm, .40 S&W, or .357 Sig to another caliber, barrel length, and grip length. The entire pistol conversion process can be done quickly and without any tools.

This Caliber X-Change Kit allows shooters to convert their P320 into a carry size with 14 rounds of .357 Sig.

This P320 conversion kit 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. 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.
