Details

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.

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.

Product Questions

Product Questions

Will this grip module work with the full size p320 slide or only with the X5 slide?

Referenced product: GRIP-X5-F-943-M-BLK

The P320 X5 Grip Module will work with a regular P320 Full Size slide in 9mm, .40 S&W and .357 Sig. It should also work for P250 full size models.

Rate the answer?
Is this compatible with the unupgraded p320 fire control group?

Referenced product: CALX-320F-357-BSS

All current Caliber X-Change kits can be used with a non-upgreaded P320. Only upgraded kits can be used with upgraded firearms though. Essentially non-upgraded firearms can accept upgraded or non-upgraded CALX kits.

Rate the answer?
Will this P320 full size .357 Sig full slide assembly work on a P320 compact 9mm pistol frame that has a manual safety?

Referenced product: CALX-320F-357-BSS
