SIG Sauer P365-XMACRO “Agency Vault” 9mm Luger with ROMEO-X Optic — Law Enforcement Allocation, 17+1, 3.7" Barrel

Developed for duty use, this XMACRO features SIG’s modular Fire Control Unit, allowing easy grip or slide swaps without gunsmithing. The matte-black Nitron slide is factory-machined for optics and retains XRAY3 day/night sights that co-witness through the ROMEO-X.
Despite its slim profile, the extended macro grip houses 17-round magazines, giving it duty-grade capacity while maintaining P365 ergonomics. A flared magwell speeds reloads, and a full 1913 three-slot rail accepts standard lights or lasers.
The carbon-steel 3.7" barrel pairs with a finely tuned striker-fired action and a flat-faced trigger that breaks cleanly for repeatable accuracy. Front and rear slide serrations offer confident manipulation in all conditions.
Originally introduced in 2022, Agency Vault units like this one were earmarked for police and government contracts. Availability to civilians is strictly limited to aftermarket channels, adding collectibility to its practical appeal.
