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.

Customer Reviews

Customer review Review by Happy Wentworth
Kit is of high quality, I love that it comes with the sig night sites,, only 2 complaints that I have is the time frame in which it took to get it in, which was about 3 months and the other thing is would have liked to have 2 additional 14 round mags come with the deal for the money. Other then that I Love the mogularity that sig offers in the P320 (Posted on 7/17/2017)
