The Sig Sauer Cal-X Kit P320 9mm 10-Round Full-Size Black gives P320 owners a complete caliber exchange package in one streamlined bundle. Designed around the proven P320 platform, this kit includes a full-size slide assembly, barrel, recoil spring, grip module, and a 10-round magazine, letting you configure a compliant full-size 9mm setup using your existing fire control unit.

This configuration is ideal for range sessions, training, or home protection where a full-size grip and sight radius are preferred. With its 10-round magazine, it also suits shooters in capacity-restricted regions who still want the handling of a full-size P320. The kit reflects Sig Sauer’s focus on modularity, reliability, and clean, functional design.
