Sig Sauer 8900031 P320 Grip Module Carry (Small Grip Module) 9mm Luger/40 S&W/357 Sig, Black Polymer, Fits P320 (Manual Safety)

The Sig Sauer 8900031 P320 Grip Module Carry is a small-frame polymer grip assembly engineered for shooters seeking a more compact platform without sacrificing ergonomic control or modular versatility. This carry-size module represents Sig Sauer's commitment to adaptability—the P320's modular architecture allows users to reconfigure their pistol for different roles, and the 8900031 specifically addresses operators and civilians who prioritize concealability and reduced footprint for daily carry or duty use.

Built from durable black polymer, this grip module features a manual safety, making it compatible with 9mm Luger, .40 S&W, and .357 Sig caliber fire control units. The small grip profile reduces overall pistol dimensions while maintaining the structural integrity and reliability Sig Sauer platforms are known for. The carry-size frame delivers measurably reduced grip circumference, allowing shooters with smaller hands or those in tight-quarters environments—patrol vehicles, plainclothes carry, close-quarters training—to maintain consistent indexing and trigger control. The manual safety mechanism adds a secondary mechanical layer for users who operate in environments where positive control of the weapon requires that additional step.

This grip module is ideal for law enforcement personnel, armed security professionals, and serious shooters transitioning to a smaller platform without changing trigger assemblies or firing characteristics. Modular grip replacement is straightforward—no gunsmithing required—making the 8900031 a cost-effective platform upgrade. Those already running the P320 platform can expand their system's flexibility; those new to the P320 lineup can select carry-size ergonomics from the start. The black polymer finish resists corrosion and reduces visual signature compared to metallic alternatives, while maintaining the structural durability required for duty-cycle use.
