Sig Sauer P320 Compact X-Change Kit 9mm Luger Handgun Conversion Kit - Black

The Sig Sauer P320 Compact X-Change Kit gives your modular P320 platform a complete transformation without buying a whole new gun. This 9mm Luger conversion kit includes everything you need to swap your fire control group into a fresh configuration: a complete slide, barrel, recoil spring assembly, grip module, and magazine. It's the modular pistol concept taken seriously—remove your P320's serialized fire control group from your current setup, drop it into this kit, and you've got a new platform ready to run.

The compact footprint makes this kit ideal if you're looking to downsize from a full-size P320 or if you need a more packable option for carry, training, or duty work. The slide features reflex optic compatibility, so if you're running a mounted red dot on your existing P320 setup, you can carry that integration forward. This is genuine modularity—the kind that lets shooters tune their P320 to different roles without duplicating the regulated fire control group.

Note that X-Change kits are engineered for P320 pistols without a manual safety. If your current P320 has a thumb safety, verify compatibility before ordering. The right-hand configuration works for standard grip orientation. This kit is a smart move for shooters who've already invested in the P320 ecosystem and want to expand its versatility without the cost and paperwork of a second complete gun.

Frequently Asked Questions

Will this X-Change kit work with my P320 that has a manual safety?

No. Sig Sauer X-Change kits are not available for P320 models with a manual safety. Make sure your fire control group is a non-safety variant before ordering this kit.

What do I need to do to use this kit?

Remove the fire control group (the serialized lower receiver) from your current P320, then install it into this kit's grip module. The fire control group is what you register and own legally—everything else swaps. No gunsmithing required.

Does this kit include everything I need to run it?

Yes. The kit includes a complete slide, barrel, recoil spring assembly, grip module, and one magazine. You only need to supply your existing fire control group.

Can I mount a red dot on the slide?

Yes. The slide is reflex optic compatible, so you can mount a red dot sight if you're running one on your existing P320 setup.
