Sig Sauer Electro-Optics SORX1270 Romeo-X Compact Black 1x24mm Illuminated Green Circle w/Dot Reticle RX Footprint Mount

The Sig Sauer Romeo-X Compact is a 1x24mm illuminated red dot sight purpose-built for optics-ready pistols, particularly the P365 family and other Sig platforms. If you're running a modern duty or defensive pistol with a milled slide, this compact reflex sight gives you a fast, reliable aiming solution without the bulk or weight of traditional magnified optics. The open-emitter design keeps your sight picture clear and your field of view unobstructed—critical when every millisecond matters on the draw or at close quarters.

Built on Sig's proven military heritage, the Romeo-X Compact brings lessons learned from the MIL-SPEC ROMEO-M17 into a streamlined civilian package. The CNC-machined 7075 aluminum housing is tough enough for duty carry, while the ultra-low deck height (just 0.94 inches) lets you co-witness with your standard iron sights for immediate fallback aiming if needed. Sig engineered this sight with an intuitive side-load battery compartment and motion-activated illumination (MOTAC) so you aren't wasting battery life or fiddling with switches when speed counts. The included CR1632 battery is rated for 20,000 hours of runtime, and the waterproof IPX-7 rating means rain, sweat, and rough handling won't compromise your optic.

The illuminated green circle with central dot gives you multiple aiming references—use the dot for precision work or the outer ring for rapid target acquisition. Fifteen illumination levels (12 daytime, 3 night-vision compatible) let you dial in your ideal brightness without washing out your sight picture in any light. Adjustment travel is generous at 80 MOA windage and elevation, giving you the flexibility to zero on different platforms or dial for extended ranges if you ever run this sight on a rifle-mounted adapter.

This is U.S.-designed and assembled, and it ships with everything you need: mounting screws for multiple footprints (including 7075 aluminum), a Torx wrench kit for easy adjustment, and a full set of mounting hardware. The RX footprint (Shield RMS-c compatible) is standard on Sig's optics-ready pistols but also fits many aftermarket and competing platforms—double-check your slide's mount before ordering if you're running a non-Sig platform.

Frequently Asked Questions

Will the Romeo-X Compact fit my Sig P365?

Yes. The Romeo-X Compact is specifically designed for the Sig P365 family of optics-ready pistols. It mounts directly using the RX footprint (Shield RMS-c compatible). Always verify your slide has the correct milling before purchasing; if you're uncertain, contact Sig or your gunsmith to confirm compatibility.

Does this red dot work with night vision?

The Romeo-X Compact includes three night-vision compatible illumination settings in addition to twelve daytime levels, allowing you to use the sight with night-vision devices. The green reticle and illumination are optimized for NV compatibility.

Can I use this sight on my standard iron sight pistol?

The Romeo-X Compact is an optics-ready sight designed for milled or cut slides. It cannot be installed on a standard pistol slide without professional milling. If your pistol does not have an optics cut, you'll need to have a gunsmith mill the slide to accept the RX footprint mount.

What's included in the box?

The package includes the sight itself, a CR1632 battery (installed and ready to use), mounting screws in three lengths (M3x0.5 and two M4x0.7 variants), a T10 Torx wrench, a T6 Torx wrench, and an operator's manual. Everything you need for installation is included except the gunsmithing—if mounting on a non-optics-ready slide, professional installation is required.
