The Sig Sauer P365/P365-XMacro grip module in black (brand part no. 8901180) is the serialized frame that anchors a P365 or P365-XMacro fire control unit, giving shooters a factory-fit foundation for a carry or range build. Sig Sauer machines a true 1913 accessory rail into the dust cover for lights and lasers, and three interchangeable backstraps (small, medium, large) ship in the box to dial in hand fit, with the medium backstrap preinstalled. The module is compatible with 17-round P365-XMACRO magazines and includes a manual safety cut. Among frame and chassis parts in the semi-auto handguns category, this grip module favors shooters building or upgrading a P365-platform pistol.
