This Sig Sauer P320 X-Series Carry Grip Module is a premium factory upgrade finished in a black 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 "Small" circumference "Carry" length frame provides a slimmer profile for easier trigger reach while maintaining a full-size grip for increased magazine capacity and a compact-length rail for 3.9-inch slides. This assembly comes ready for installation with a pre-installed, reversible magazine catch and is compatible with internal tungsten weights for added balance.
