This Sig Sauer P320 X-Series Full Size Grip Module is a premium factory upgrade finished in a durable coyote tan polymer for Fire Control Units without a manual safety. It features the signature X-Series ergonomics, including a deep trigger guard undercut and an extended beavertail, which allow for a higher grip and improved recoil management. The "Large" circumference "Full Size" frame provides a fuller profile for shooters with larger hands while maintaining a full-length rail for 4.7-inch slides and a full-size grip for maximum magazine capacity. This assembly comes ready for installation with a pre-installed, reversible magazine catch and is compatible with internal tungsten weights for added balance.
