The Sig Sauer P320 Full Size X-Change Kit in 9mm Luger is a caliber conversion system that lets you transform your P320 into a different cartridge without buying an entirely new handgun. If you already own a P320 and want to explore other centerfire options, the X-Change kit gives you the flexibility to swap calibers by simply breaking down and reassembling your gun — no gunsmith required. This modular approach makes it a smart investment for shooters who want versatility on the range or in the field.
The kit includes a complete slide and barrel assembly, a grip module, and a magazine tuned for 9mm Luger, all in black. The grip module supplied with this kit is medium-sized, which works across Sig's X-Change lineup regardless of your chosen caliber or barrel length. The X-Change system's core strength is its simplicity: swap the upper receiver group and magazine, and you're running a different round. It's the kind of flexibility that appeals to competitive shooters, hunters who want to match different loads to different game, or anyone curious about how a different caliber performs in the same proven platform.
One important compatibility note: X-Change kits are not compatible with P320 models that have a manual safety. If your P320 has a frame-mounted safety, this kit won't work with it. Make sure you're starting with a standard (non-safety) P320 Full Size before ordering. Otherwise, you're looking at a straightforward modular system that respects the original design and keeps you shooting the gun you already trust.
