SIG Sauer 8901180 Grip Module 9mm 17-Round Manual Safety

The SIG Sauer 8901180 Grip Module 9mm 17-Round Manual Safety is a factory OEM replacement grip frame engineered for the P320 platform, one of the most versatile modular handgun systems in service with military, law enforcement, and civilian operators worldwide. This grip module serves as the serialized lower receiver component and fire control housing, making it an essential part for those building custom P320 configurations or replacing worn original equipment. Whether you're rebuilding a duty weapon, upgrading to a different caliber, or customizing your carry setup, this grip module provides the foundation for a reliable, field-proven platform.

Manufactured to SIG Sauer's exacting standards, this grip module is specifically configured for 9mm operation with a 17-round magazine capacity and manual safety lever, delivering a traditional carry option preferred by many trained shooters. The modular design allows you to swap upper assemblies, barrels, and slides without requiring a complete firearm rebuild—a tactical advantage when maintaining multiple configurations or transitioning between compact and full-size setups. The grip frame houses the serialized fire control group and is machined from reinforced polymer composite, providing durability while maintaining the lightweight handling characteristics that define the P320 platform. The manual safety mechanism offers controlled, positive engagement for shooters who prioritize tactile safety confirmation.

This grip module is compatible exclusively with SIG Sauer P320 upper assemblies and fire control groups chambered in 9mm Luger, making it ideal for those already invested in the modular ecosystem or those looking to enter it with a proven platform. Installation requires basic armorer-level knowledge—drift out the trigger group and fire control lever, insert the module, and reassemble. Law enforcement armorer shops, military gunsmiths, and experienced civilian shooters routinely stock this component for duty weapon maintenance and custom builds. The manual safety configuration appeals to traditional shooters and those operating under department or agency protocols requiring external safety levers.
