Sig Sauer P320 Caliber X-Change Kit Installation & Range Test

Posted by Jordan on Aug 27th 2018

The Sig Sauer Caliber X-Change kits are a huge part of what makes the P320 so versatile. The P320's serial number is engraved on the fire control unit, which can be easily removed from the pistol, allowing you to swap frames, slides, and barrels without ever replacing the actual serialized unit. This makes the P320 easier to convert than any other pistol on the market. The user can swap between 9mm, .40 S&W, or .357 Sig, as well as changing between subcompact, compact, carry, or full size. The swap can be done quickly and easily by anyone and does not require the use of any tools.

In this video we show you just how easy it is to install your Caliber X-Change Kit, plus we take the P320 out in the range for some test firing!
