The SIG Sauer ROMEO-X Pro Red Dot Sight is a premium open-reflex pistol red dot sight built on the DeltaPoint Pro footprint — one of the most widely supported optic cuts on full-size and compact pistols. A distortion-free aspherical lens and clean window make it fast on target and easy to co-witness.
This model runs a selectable 2 MOA dot / 32 MOA circle reticle (red), with MOTAC + MAGNETAC activation, 15 brightness settings (3 night-vision), a convenient top-loading CR2032 tray and IPX8 sealing.

Frequently Asked Questions
What footprint is it?
DeltaPoint Pro — fits DPP-cut slides and optics-ready pistols with a DPP plate.
Pro vs Compact?
The Pro is the larger DeltaPoint Pro optic; the Compact uses the slim RMSc footprint for carry pistols.
Can I change the battery without removing it?
Yes — the CR2032 loads from the top, so zero is retained.
