SIG SAUER ROMEO-X Enclosed Compact Circle-Dot Sight Black

SIG SAUER ROMEO-X Enclosed Compact Circle-Dot

The SIG SAUER ROMEO-X Enclosed Compact SORX1400 brings a protected emitter and a highly usable circle-dot aiming system to slim, optics-ready pistols. This exact black model uses the Compact, or Shield RMSc, footprint and combines a 2 MOA center dot with a 32 MOA circle. Its 1x, parallax-free reflex format keeps both eyes open and the target in view, while the enclosed optical system helps keep dust, moisture and debris away from the emitter. The result is a compact sight built for everyday carry, training and defensive use where a clear aiming reference and dependable construction matter.

Fast Circle-Dot Reticle

The red circle-dot reticle supports both rapid presentation and deliberate aiming. The 32 MOA circle is easy to acquire as the pistol reaches eye level, while the 2 MOA center dot provides a finer reference for more precise shots. Fifteen illumination settings provide 12 daylight levels and three night-vision-compatible settings, allowing the shooter to match reticle intensity to changing light. Independent side controls make brightness changes straightforward without blocking the sight picture.

SIG SAUER’s MOTAC motion-activated illumination turns the reticle on when motion is detected and powers it down during inactivity to conserve energy. A compatible holster can also work with MAGNETAC magnetic activation, switching the optic off while holstered and returning it to the previous setting when drawn. The rated runtime is up to 20,000 hours at a medium setting with one CR1632 battery.

Enclosed, Low-Profile Construction

The housing is CNC-machined from 7075 aluminum and surrounds a sealed, argon-purged optical system. Unlike an open-emitter design, the enclosed arrangement places glass in front of and behind the emitter path, reducing the chance that lint, rain or field debris will interrupt the projected dot. IPX-7 waterproofing adds confidence around wet weather and routine exposure.

A distortion-free aspherical lens helps maintain a natural view through the optic, while SpectraCoat anti-reflection treatment improves light transmission and limits distracting surface reflection. D.A.R.C. coatings and brightness settings are optimized for use with compatible Gen 3+ night-vision equipment. The sight also uses SIG SAUER’s beryllium-copper flexure-arm adjustment system for a durable windage and elevation mechanism.

Compact Footprint and Practical Battery Access

SORX1400 measures approximately 1.62 inches long, 1.23 inches wide and 0.94 inch high, with a weight of about 1.1 ounces including the battery. Its Shield RMSc-pattern footprint is intended for compatible micro-compact optic cuts, including SIG P365-family applications. Always confirm the exact slide cut, screw pattern and required hardware for the host pistol before installation.

The side-mounted battery compartment allows the CR1632 cell to be replaced without removing the optic from the slide. That design helps preserve the installed zero and avoids the extra mounting work associated with bottom-loading battery systems. The ultra-low deck height is designed to support co-witness with standard-height iron sights on compatible pistols.

Purpose-Built for a Slim Optics-Ready Pistol

The ROMEO-X Enclosed Compact is a strong choice for shooters who want the small mounting pattern of a micro-pistol optic without leaving the emitter exposed. Its circle-dot reticle, low deck height, side battery access and motion management features are all oriented toward a pistol that may be carried often and used in varied conditions. For proper performance, mount the optic according to SIG SAUER and firearm-manufacturer instructions, verify screw length and torque, and confirm zero with the intended ammunition before use.
