SIG Sauer P365 XMacro Agency Vault 9mm – Factory ROMEO-X Compact Optic, 17+1, Limited-Edition LE Allocation

What’s Included
- SIG Sauer gray hard plastic case
- Sig Sauer ROMEO-X Compact red-dot sight (factory-installed, closed-emitter, 7075-T6 aluminum housing)
- Three 17-round SIG Sauer steel magazines
- Interchangeable grip backstraps

The Agency Vault XMacro pairs a matte-black Nitron-finished stainless slide with forward and rear serrations, an optic cut that mounts the ROMEO-X low enough to co-witness the X-Ray3 day/night sights, and a 5-slot MIL-STD-1913 accessory rail on the extended polymer grip module.
Inside, the 3.7-inch stainless barrel uses the same Nitron treatment for corrosion resistance. The striker-fired action features the flat-faced X-Series trigger for a consistent break and short reset. SIG’s universal P365 Fire Control Unit allows future caliber or frame swaps without gunsmithing.
The ROMEO-X Compact red dot provides a bright red reticle with multiple intensity settings, enclosed-emitter reliability, and 7075-T6 aluminum construction—all factory-zeroed by SIG. Combined with the 17-round flush-fit magazine, this XMacro delivers full-size capacity in a carry-length slide.
As a limited-edition law-enforcement SKU (part number W365XCA-9-BXR3P-RXX), examples like this are uncommon on the commercial market, adding collectability to its practical performance.
