SIG Sauer GRIPMODXCA943SMBLK P320 Grip 3.9" Pistol

The SIG Sauer GRIPMODXCA943SMBLK P320 Grip Module X-Series Carry is a modular grip assembly engineered for operators seeking to convert their P320 firing control units into a dedicated compact-carry platform. This grip module accepts 9mm Luger, .40 S&W, and .357 Sig cartridges, accommodating barrel lengths of 3.90 inches and 4.70 inches. Built from black polymer, the X-Series Carry grip delivers the ergonomic profile and accessory compatibility that define the P320 platform's modularity—allowing users to swap calibers and barrel lengths without replacing the entire pistol.

The X-Series grip module represents SIG's refinement of the P320 ergonomic ecosystem. Unlike earlier grip variants, the X-Series Carry is optimized for concealment-oriented carry while maintaining the mechanical reliability and trigger reach consistency that operators expect. Compatibility extends to P320 slides and barrels chambered in the supported calibers; the module requires a separate firing control unit to complete the assembly. Critical note: this grip module is designed for magazines bearing the SIG Mark baseplate, not those marked "SIG SAUER." This specification detail prevents feeding failures and ensures reliable operation in duty or training scenarios.

This grip module serves law enforcement personnel, armed security professionals, and civilian carriers who have already invested in P320 ecosystem components and need to configure a smaller-frame variant for appendix or inside-the-waistband carry. The modular design eliminates the need to purchase a complete second pistol while transitioning to a reduced footprint. Field deployment across domestic and international agencies has validated the P320 platform's durability and the X-Series line's ergonomic refinement. Whether for duty transition, range experimentation across calibers, or backup platform configuration, this grip module provides the foundation for a purpose-built compact defensive tool.
