Sig Sauer P320 X-Series Grip Module 9mm Luger, 40 S&W, 357 SIG Large - Coyote Tan

The Sig Sauer P320 X-Series Grip Module is the factory polymer grip housing for the modular Sig P320 pistol platform. This full-size X-Series module accepts a P320 fire control unit (FCU) so the shooter can configure or re-build a P320 around a single serialized chassis while retaining caliber flexibility across 9mm Luger, 40 S&W, and 357 SIG.

This variant is the Large grip circumference, molded in Coyote Tan polymer with the standard X-Series grip texturing. It is a direct factory replacement grip housing for the full-size P320 slide and barrel combination (4.70" slide) and drops onto any standard P320 fire control unit. At just 4 oz, the module integrates the magazine well and serves as the structural grip foundation of the pistol, accepting standard P320 magazines.

Please note that this grip module is a non-serialized polymer accessory. On the P320 platform, the serialized, regulated part is the fire control unit (FCU), which is sold separately. A complete P320 pistol also requires a slide assembly, barrel, and magazine - all sold separately.

Whether matching a Coyote Tan slide, balancing a full-size slide on a larger hand, or simply refreshing a worn factory module, the Sig Sauer GRIPMODXF943LGCOY offers a true factory-direct upgrade path.
