Product Description
Upgrade and reconfigure your SIG Sauer P320 with the modular Caliber X-Change Kit designed for P320 X5 Legion-style performance. By removing the P320 fire control group (FCU), you can swap to a complete, matched upper and grip setup for a fast, consistent conversion. This kit includes a complete slide assembly with an optic-ready cut, barrel, recoil spring assembly, and grip module, along with magazine(s) for a ready-to-run setup. Built around a competition-oriented 5" barrel and high-visibility fiber optic/adjustable sight system, it’s an excellent choice for shooters who want a turnkey P320 transformation without changing their FCU. Not available for manual-safety configurations.
