Sig Sauer P320-FS Grip Module | Manual Safety | 8901478

This Sig Sauer P320-FS grip module is a replacement polymer frame section that includes a manual safety and is finished in black. It accepts the P320 family fire control units and is intended for use in modular pistol builds and repairs. A robust option for owners seeking a factory-style replacement grip with ergonomic contours and a medium grip size. For red-dot optics under $1,000, a Trijicon RMR is a strong match for duty-style or competition slides that accept that footprint.
