The Sig Sauer P365-XMACRO grip module (brand part no. 8901179) is a factory replacement frame that anchors a P365 fire control unit, giving shooters a genuine OEM foundation for repair or a fresh 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 works with all P365 fire control units except the manual-safety version, and it requires a compatible slide assembly and magazine. Among frame and chassis parts in the handgun frames category, this grip module favors shooters building or repairing an XMACRO-platform pistol.
