Quick Overview

Convert your P320 to a compact .357 Sig. This doesn't work with .45 ACP P320's. Includes grip shell, full slide assembly with SIGLite night sights pre-installed and one 13rd magazine.

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 compact size .357 Sig. It is not compatible with .45 ACP P320's.

Product Questions

I have a sig p250 compact 9mm and would like the kit to change it to a 40 cal or 357. Is this kit available

Response Date: Apr 2, 2019

Unfortunately all P250 kits have been discontinued. We don't have a solution. You would need to look on the used market.
