The SIG Sauer P365-XMacro Grip Module (SIG part no. 8901182) is the factory replacement module for the P365-XMacro, built to accept the pistol’s 17-round magazines and give shooters a way to fine-tune fit. SIG equipped this module with a true 1913 accessory rail for mounting lights or lasers, along with three interchangeable backstraps — small, medium, and large — to match different hand sizes. The medium backstrap ships preinstalled, so the module is ready to run out of the box while still leaving room to adjust. P365-XMacro owners replacing a damaged module or dialing in grip fit choose this factory part to keep everything OEM.
