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.

P320 Caliber X-Change Kit The modular P320 allows you to select any of several centerfire calibers. Just disassemble the pistol and reassemble it with the X-Change Kit's barrel/slide assembly, grip module, and magazine.
