Sig Sauer GRIPMODXF943MCOY P320 Grip Module X-Series (Medium Size Module), 9mm Luger/40 S&W/357 Sig, Coyote Polymer, Fits Full Size Sig P320 (4.70")

The Sig Sauer P320 Grip Module X-Series in Coyote is the foundation for building a customized, modular P320 platform. This medium-size grip module accepts your existing P320 firing control unit and pairs with a full-size 9mm Luger, .40 S&W, or .357 SIG slide and barrel to create a complete X-Series pistol. It's the modular flexibility that makes the P320 system one of the most adaptable duty and sport pistols available—swap calibers, sizes, and configurations without buying new guns.

If you're already running a P320 and want to explore a different chambering or build a dedicated X-Series version, this grip module is your starting point. The coyote polymer finish offers a tactical aesthetic and proven durability. One essential detail: X-Series grip modules require magazines with the SIG mark on the baseplate, not the older "SIG SAUER" marked baseplates. This module does not include the extended magwell or internal weight found on some other X-Series builds, so verify compatibility with your intended slide and barrel assembly before ordering.

Whether you're building a range gun, a competition rig, or expanding a multi-caliber P320 collection, this grip module delivers the quality and precision Sig is known for. The modular design means you control the final configuration—this is just the beginning.
