The P365-XMACRO ROMEO-X Package is SIG Sauer’s newest, full-capacity P365 variant, offered here from the Agency Vault law-enforcement allocation.

This Agency Vault example carries the 66G serial prefix identifying law-enforcement allocation. Buyers gain a pistol built to agency specs yet released only through aftermarket channels.
The XMACRO frame houses SIG’s modular fire-control unit, interchangeable backstraps, and a detachable mag-well that also accepts standard P365 magazines—making it the first P365 to offer true grip-size customization.
A cold hammer-forged 3.7-inch carbon-steel barrel pairs with a Nitron-finished slide that is factory optic-cut for Shield RMS/ROMEO-X footprints. Front and rear serrations enhance manipulation, and a five-slot MIL-STD-1913 rail supports lights or lasers.
The flat-faced striker trigger provides a consistent break, while XRAY3 night sights serve as co-witnessed backups thanks to their integration into the ROMEO-X housing with aspheric glass and a side-load battery tray.
Despite its 17+1 capacity, the P365-XMACRO maintains the P365 family’s slim profile, measuring just 1.1 inches at the widest point—delivering full-size firepower in a compact carry package.
