Sig Sauer P365 XMACRO Comp w/Romeo Compact Handgun 9mm Luger 17rd Magazines(2) 3.1" Barrel
The Sig Sauer P365 XMACRO Comp is a slim, high-capacity 9mm built for shooters who want serious firepower without sacrificing carry comfort. This compact pistol packs 17 rounds into a profile that feels at home in an appendix rig or waistband holster—a balance most guns simply don't strike. The integrated compensator tames recoil and speeds up follow-up shots, while the optic-ready slide and included Romeo Compact red dot give you a modern, shootable platform straight out of the box.
What makes the XMACRO stand out is its engineering. The new macro-compact grip module and slim 1.2-inch width keep the gun remarkably concealable for a 17-rounder, while the standard 1913 accessory rail means you can mount lights or lasers without proprietary mounts. The flat striker trigger is clean and predictable, and the XRAY3 day/night sights work with or without the red dot. Two steel magazines with high-visibility followers come loaded in the box.
This is a carry gun for serious shooters—whether you're running drills at the range, working defensive handgun classes, or carrying daily. It bridges the gap between micro-compact convenience and full-size capacity without feeling oversized. The Romeo Compact optic is already installed, so you get an immediately usable, shooter-centric platform.
