SIG SAUER P320 Grip Module Assembly for 9mm/.40/.357 - Medium, Coyote Tan

The SIG SAUER P320 Grip Module Assembly is the foundation of SIG's modular pistol platform—swap it out to reconfigure your P320 for different calibers and grip sizes without changing your firing control unit. This medium-frame grip module in Coyote Tan is designed for 9mm Luger, .40 S&W, and .357 SIG, making it an efficient way to build or rebuild a compact or carry-sized P320. If you already own a P320 or P250 firing control unit, a fresh grip module lets you adapt to a new role or hand size, all while keeping the trigger group and internals you know.

SIG's modular system is built on the idea that one pistol shouldn't mean one configuration. Whether you're looking to downsize from a full-size to a compact carry gun, or you want a dedicated module for a different caliber, the grip module swap is straightforward and requires only the matching slide and barrel for your chosen caliber. Coyote Tan is a proven field finish that balances aesthetics with practical concealment and resists glare in harsh light.

This is a genuine SIG SAUER OEM part, so you get the same fit, finish, and reliability that comes standard on factory P320 pistols. Durable polymer construction and aggressive texturing make for a secure grip, and the ergonomic design works for both right and left-handed shooters.
