SIG SAUER ROMEO-X PRO ENCLOSED CD FDE

SIG SAUER ROMEO-X Enclosed PRO Circle-Dot in FDE

The SIG SAUER ROMEO-X Enclosed PRO SORX1302 combines a sealed emitter system with the familiar PRO mounting footprint for shooters who want a rugged, low-profile pistol optic. This exact model is finished in flat dark earth and uses SIG SAUER’s circle-dot reticle. Its enclosed optical path helps keep dust, lint, moisture, and airborne debris away from the emitter, while the compact housing preserves a streamlined profile on a compatible optic-ready handgun.

SIG builds the sight around a CNC-machined 7075-aluminum housing and an argon-purged optical system. The construction is designed for hard use without adding unnecessary bulk. An aspherical glass lens controls distortion across the viewing area, and SpectraCoat anti-reflection coatings support light transmission and a clear sight picture. The result is an aiming system designed for fast visual acquisition at practical handgun distances.

Low profile with a PRO footprint

The ROMEO-X Enclosed PRO uses SIG SAUER’s PRO footprint, which corresponds to the DeltaPoint Pro mounting pattern. It is intended for compatible optic-ready pistols and measures approximately 1.83 inches long, 1.23 inches wide, and 0.94 inch high. Its low deck height is engineered to make co-witnessing with standard-height iron sights possible on appropriate slide and sight combinations. Because mounting cuts, screw specifications, and iron-sight heights vary, confirm compatibility with the host pistol and mounting hardware before installation.

Circle-dot reticle and illumination controls

This SORX1302 configuration uses a red circle-dot aiming pattern. The surrounding circle can help guide the eye toward the central aiming point, giving the shooter an intuitive visual reference for rapid presentation while retaining a precise center reference. Fifteen illumination settings are available: twelve for daylight use and three optimized for use with compatible night-vision equipment. Independent side controls keep brightness changes accessible without obstructing the viewing window.

MOTAC motion-activated illumination powers the reticle when movement is detected and turns it down when the sight is idle, helping conserve the battery between uses. SIG rates runtime at up to 20,000 hours under appropriate conditions. The optic runs on one CR1632 battery housed in a side-loading compartment, so routine battery replacement does not require removing the sight from the slide or intentionally disturbing the established zero.

Mechanical adjustment and environmental protection

The patented beryllium-copper flexure system supports precise reticle adjustment within the compact enclosure. SIG specifies 70 MOA of total elevation travel and 65 MOA of total windage travel, providing useful adjustment range for properly mounted compatible pistols. The enclosed system carries an IPX7 waterproof rating, adding protection against rain, incidental immersion, and demanding field conditions. As with any sighting system, mounting screws should be installed to the firearm or mount maker’s specified torque and the zero should be confirmed with the intended ammunition.

What to verify before ordering

This listing is for the optic identified by SIG SAUER part number SORX1302 and UPC 798681702114. It is the enclosed PRO-footprint, circle-dot, flat dark earth model. It is not the smaller Compact-footprint version, and the optic’s color, footprint, and reticle should all be matched to the intended pistol before purchase. Adapter plates may be required on some non-SIG pistols, even when the slide is marketed as optic ready.

The ROMEO-X Enclosed PRO is well suited to owners who prioritize a protected emitter, accessible controls, convenient battery service, and a low mounting profile. Its combination of sealed construction, durable materials, useful illumination range, and compatibility with the established PRO footprint makes it a practical option for carry, duty, training, and general range use on a properly configured handgun.
