What Makes the SIG P365 XMacro a Game-Changer for Concealed Carry?
The SIG P365 XMacro pistol represents the logical evolution of the revolutionary P365 platform, pushing capacity boundaries while maintaining impressive concealability. By delivering 17+1 rounds in a frame barely over an inch wide, SIG created a new category that bridges micro-compacts and traditional duty pistols.
SIG SAUER, headquartered in Newington, New Hampshire, developed the XMacro as the high-capacity answer for shooters who wanted P365 concealability with Glock 19-level capacity. The platform builds directly on the P365's proven fire control unit and magazine technology while incorporating a longer "Macro" grip module that accommodates the flush-fit 17-round steel magazines.
The P365 XMacro lineage traces through the original P365's revolutionary double-stack magazine design, the P365X's optics-ready slide, and the P365 XL's extended barrel and grip. The XMacro combines lessons from each variant while adding features like the standard Picatinny rail that smaller P365 models lacked. The COMP variant introduced integrated compensation for reduced muzzle flip.
SIG designed the P365 XMacro for concealed carriers who refuse to compromise on capacity. The platform targets appendix carry and inside-the-waistband users who want maximum rounds without the bulk of traditional double-stack compacts. Competition shooters, home defenders, and anyone prioritizing firepower in a slim package find the XMacro compelling.
