This Sig Sauer P320 X-Series Compact Grip Module is a premium factory upgrade finished in a 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 "Medium" circumference frame is optimized for 9mm, .40 S & W, and .357 SIG setups, specifically fitting compact 3.6-inch or 3.9-inch slide lengths. This assembly comes ready for installation with a pre-installed, reversible magazine catch and is compatible with internal tungsten weights for added balance.
