Sig Sauer Electro-Optics SORX1480 Romeo-X Enclosed Compact Black 1x24mm 3MOA Green Dot Reticle RX Footprint Mount

The Sig Sauer Romeo-X Enclosed Compact is a sealed red dot sight built for serious duty on concealed-carry and compact pistols. Engineered with the same reliability Sig has proven in military service, this 1x24mm optic delivers a crisp 3 MOA green dot reticle in a low-profile package that won't interfere with standard iron sights. The RX footprint mount (Shield RMS-c compatible) and ultra-low 0.94-inch deck height let you mount it on everything from Shields to modern carry guns without sacrificing sight picture or ergonomics.

What sets the Romeo-X Enclosed apart is its construction: a rugged 7075 aluminum housing with a fully sealed and enclosed optical system keeps dirt, moisture, and dust away from the lens and internals. The aspherical glass delivers distortion-free glass from edge to edge, and Sig's patent-pending beryllium copper flexure arm absorbs recoil without losing zero. Motion-activated illumination (MOTAC) stretches battery life to an impressive 20,000 hours, and the side-mounted battery compartment (single CR1632) is dead-simple to access without removing the sight from your gun.

Fifteen brightness settings—twelve for daylight, three for night vision—cover everything from dim indoor hallways to bright outdoor ranges. The sight is waterproof to IPX-7 spec and fully assembled in the USA. Total elevation and windage travel (65 and 70 MOA respectively) gives you room for zeroing and holdovers on smaller frames where rail space is precious.

Specifications

Frequently Asked Questions

Will the Romeo-X Enclosed mount on my Shield or Hellcat?

Yes. The RX footprint is the Shield RMS-c specification, which fits modern carry guns with Shield-compatible cut patterns. If your pistol has a standard Shield RMS-c footprint, this sight will drop straight on without adapters.

Can I use this sight with my existing iron sights?

Absolutely. The ultra-low 0.94-inch deck height is designed for seamless co-witness with standard-height iron sights, so you can keep both your irons and dot in the same sight picture.

How long does the battery last, and how do I change it?

The Romeo-X Enclosed runs for 20,000 hours on a single CR1632 battery—that's roughly 2.3 years of continuous operation. The side-mounted battery compartment lets you swap batteries without removing the sight from your pistol.

What makes the enclosed optical system important?

An enclosed and sealed system keeps dirt, dust, and moisture away from the lens and internals, which is critical for carry guns that spend time in holsters and get exposed to the elements. Combined with IPX-7 waterproofing, it gives you confidence your dot will function when you need it.
