Sig Sauer Electro-Optics SORX1390 Romeo-X Enclosed Pro Black 1x24mm 6MOA Green Dot Reticle RX Footprint Mount

The Sig Sauer Romeo-X Enclosed Pro is a 1x24mm pistol red dot built for shooters who need a durable, no-compromise aiming solution on a concealed-carry or duty handgun. Born from Sig's military-grade red-dot heritage, the Romeo-X Enclosed Pro combines a rugged CNC 7075 aluminum housing with a fully sealed optical system—eliminating the exposure and fragility of open-emitter designs. Whether you're training at the range, running drills in low light, or carrying daily, this enclosed red dot delivers the rock-solid reliability Sig is known for, paired with a low-profile mount that plays nicely with standard iron sights.

The optical system centers on an aspherical glass lens and high-efficiency point-source emitter tuned for a clean, distortion-free sight picture. Sig's patent-pending beryllium copper flexure arm absorbs recoil and impact while keeping the dot sharp and repeatable. The side-mounted battery compartment (one CR1632 cell) stays out of the way, and Motion Activated Illumination (MOTAC) stretches runtime to a claimed 20,000 hours—plenty of juice for the long haul. With 15 brightness settings (12 daylight, 3 night vision), you can dial in the right glow for any light condition without fumbling in the dark.

The Pro footprint delivers a low 0.94-inch deck height that cowitnesses naturally with standard iron sights, keeping your sight picture consistent whether you're using the dot alone or as a backup. Elevation and windage travel span 70 and 65 MOA respectively, giving you room to zero and dial. Waterproofing to IPX-7 means it'll handle dunks and heavy rain, and every unit is assembled in the USA. If you're looking for an enclosed pistol red dot that prioritizes durability, compatibility, and field-proven performance, the Romeo-X Enclosed Pro is a serious contender.

Frequently Asked Questions

Will the Romeo-X Enclosed Pro cowitness with my standard iron sights?

Yes. The Pro footprint sits at 0.94 inches in height, which allows you to cowitness naturally with standard-height iron sights. You can use the red dot alone or as a primary sight with irons as backup.

What's the battery life, and how do I change it?

The single CR1632 battery delivers approximately 20,000 hours of runtime. The side-mounted battery compartment lets you swap cells without removing the sight from your pistol, and the Motion-Activated Illumination (MOTAC) system helps extend battery life by turning the dot off when motion stops.

Is the Romeo-X Enclosed Pro sealed against water and dust?

Yes. The fully enclosed optical system and IPX-7 waterproofing rating mean it will withstand submersion and heavy rain without leaking or fogging. The enclosed design also protects the emitter from impacts, sand, and debris.

Can I adjust brightness in low light?

Absolutely. The sight offers 15 illumination settings—12 for daylight use and 3 that are night-vision compatible. You can dial the brightness up or down without night-vision gear, and the NV-safe settings preserve your night vision if you're using NVG equipment.
