Sig Sauer GRIPMODXC943SMBLK P320 Grip Module X-Series Compact (Small Size Module), 9mm Luger/40 S&W/357 Sig, Black Polymer, Fits Sig P320 (3.60" & 3.90")

The Sig Sauer GRIPMODXC943SMBLK P320 Grip Module X-Series Compact is a purpose-built replacement frame designed for shooters who need modular control over their P320 platform firearm. This small-size grip module accommodates 9mm Luger, .40 S&W, and .357 Sig ammunition, and fits Sig P320 compact models with 3.60" and 3.90" barrels. The black polymer construction provides the corrosion resistance and durability expected in tactical and professional applications while maintaining the ergonomic geometry that distinguishes the X-Series line from earlier P320 generations.

The compact small frame size reduces overall grip circumference and length, making the P320 configuration suitable for shooters with smaller hands or those prioritizing concealability without sacrificing the modular fire control group compatibility that defines the P320 platform. The X-Series geometry incorporates enhanced grip texturing and an undercut trigger guard that improves weapon control during transitions and tactical manipulation. Because the grip module is a serialized component under federal firearms regulations, this purchase requires FFL transfer and complies with all applicable firearms laws.

This module suits operators, law enforcement personnel, and sport shooters who run Sig P320 systems and require a compact profile. The ability to swap caliber-compatible fire control groups between modules—while maintaining one serialized receiver—makes the P320 platform cost-effective for shooters who train or carry in multiple calibers. Inventory of genuine OEM grip modules allows shooters to configure their P320 exactly to their specifications rather than purchasing entirely new firearms.

The P320 grip module market includes aftermarket options, but Sig Sauer OEM modules maintain factory tolerances and QC standards that ensure reliable function with duty and competition ammunition. The compact X-Series configuration has been adopted by professional and military units, confirming its real-world reliability in high-round-count training and operational environments.
