The Sig Sauer P320 Grip Module X-Series Carry in medium size gives you a platform to customize one of the most modular duty and carry pistols on the market. This black polymer grip assembly is the foundation of your P320—swap calibers, barrel lengths, and slide configurations without buying a whole new gun. The X-Series Carry module is engineered for shooters who want a purpose-built platform optimized for concealed carry and everyday use.
Built for the working shooter, this grip module accepts Sig P320 slides in both 3.90" and 4.70" barrel lengths, so you can run it as a compact carry gun or a slightly longer setup depending on your holster, hand size, and mission. The medium size module is the right choice if you wear a standard glove size or prefer a balanced grip diameter—not too slim, not too chunky. The black polymer construction is durable, resistant to the elements, and designed to last through thousands of rounds and years of carry.
Sig's modular P320 platform means this grip is compatible with fire control units and slides in 9mm Luger, .40 S&W, and .357 Sig, giving you the flexibility to reconfigure your pistol as your needs change. Whether you're a duty shooter testing different calibers, a concealed carrier who wants redundancy, or a range enthusiast who likes options, the P320 grip module approach lets you do it without excess inventory.
