Sig Sauer
The Sig Sauer 357 Sig P320 Compact Caliber X-Change Kit gives you the flexibility to run your P320 Compact in a different caliber without buying a second gun. This kit is built around Sig's modular X-Change platform, letting you swap calibers and keep the same frame and fire control group. If you're a shooter who wants to train in 357 Sig or needs a dedicated round for a specific range or hunting application, this kit lets you do it efficiently.
The 10-round magazine capacity strikes a balance between practical carry and firepower for compact shooters. Whether you're at the range working on precision drills, training for defensive scenarios, or building out a versatile duty gun, having a dedicated 357 Sig upper and magazine pairing keeps everything reliable and properly matched. Sig P320 owners appreciate the X-Change system because it eliminates guesswork—you know your round count, your setup is manufacturer-tested, and you're running components designed to work together.
This is raw modular capability for shooters who take their gear seriously and want options without compromise.
