The Sig Sauer Romeo-X Compact is a 1x24mm open-emitter red dot sight designed specifically for optic-ready compact and subcompact pistols. Built on proven military red dot technology adapted for the civilian market, this is a no-nonsense optic that prioritizes durability, quick target acquisition, and co-witness capability with factory iron sights. Whether you carry a P365, P320 subcompact, P226, or P229 in an RX-mount-compatible platform, the Romeo-X Compact delivers the speed and reliability you need for defensive shooting, sport competition, or duty carry.
The housing is CNC-machined from 7075 aluminum, the same material spec used in aerospace and precision firearms. A patent-pending beryllium copper flexure arm supports the optic while keeping weight and profile to a minimum. The 0.94-inch deck height is engineered to sit low enough that your existing iron sights remain usable for backup aiming—a practical feature that separates serious defensive optics from range toys. The side-mounted battery compartment keeps the top profile clean and won't interfere with slide-mounted carry systems. Motion-activated illumination means the dot stays on when you move and shuts down when idle, extending the already impressive 20,000-hour runtime.
The distortion-free aspherical lens keeps the reticle sharp across the entire field of view, and the 6 MOA dot is bright enough to pick up fast in daylight without overwhelming your target in low light. You get 12 daytime illumination levels plus 3 night vision settings, so you're ready for any lighting condition. The optic is waterproofed to IPX-7 and fully assembled in the U.S.A. Your package includes mounting screws in three different lengths, a T10 and T6 Torx wrench for installation, and a fresh CR1632 battery ready to go.

The Romeo-X Compact uses the RX footprint (Shield RMS-c compatible) and is designed for optic-ready versions of the Sig Sauer P365 family, P320 compact/subcompact models, P226, and P229. It mounts directly to the slide without adapters on these pistols.
Yes. The deck height of 0.94 inches is specifically engineered to co-witness with factory standard-height iron sights, so you have a backup aiming solution if the optic fails.
The CR1632 battery lasts up to 20,000 hours of use, and one is included in the package. The motion-activated illumination (MOTAC) feature automatically powers down when stationary, significantly extending real-world battery life beyond that rating.
You receive the optic, an operator's manual, three different mounting screw sets (M3x0.5 and two M4x0.7 lengths), a T10 and T6 Torx wrench for installation and adjustment, and a CR1632 battery ready to install.
