SIG Sauer P365-XMACRO COMP 9mm, ROMEO-X Compact Red Dot, Integral Compensator, 3.1 in Barrel, 17+1, Law Enforcement Surplus
This P365-XMACRO COMP stands out as a factory-compensated, high-capacity 9mm with an installed SIG Sauer ROMEO-X Compact red dot. Built on the macro-size grip module with a true M1913 full-length rail, it combines a 3.1 in barrel, stainless Nitron slide, and X-RAY3 day/night sights. This pistol was issued for law enforcement personnel; this surplus model has been made available to the civilian market.
The COMP configuration integrates the compensator into the slide for a clean, purpose-built package. The XMacro grip module adds a beavertail, aggressive texture, and a lanyard hole while maintaining a 17+1 capacity. An RMSc-footprint optic cut houses the ROMEO-X Compact, and its low deck height supports co-witness with standard-height sights.
The striker-fired, locked-breech action pairs with a flat-faced trigger. Materials are duty-focused: a carbon steel barrel, stainless steel slide with Nitron finish, polymer grip module, and a stainless receiver. Controls are streamlined with no external manual thumb safety. Forward cocking serrations aid manipulation, and the front sight is mounted on the comp block with a dovetailed rear notch behind the optic.
Factory X-RAY3 day/night sights back up the ROMEO-X Compact, which includes side brightness controls. The full-length true M1913 accessory rail supports common duty lights. As a recent-release XMACRO variant, this example presents as-new with a mirror-clean bore, and its serial matches the factory case label.
