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 optic footprint does the SIG Sauer ROMEO-X Pro use?
The SIG Sauer ROMEO-X Pro uses the DeltaPoint Pro (DPP) footprint, so it fits DPP-cut slides and optics-ready pistols fitted with a DPP adapter plate.
What is the difference between the ROMEO-X Pro and the ROMEO-X Compact?
The SIG Sauer ROMEO-X Pro is the larger optic and uses the DeltaPoint Pro footprint; the ROMEO-X Compact uses the slimmer RMSc footprint for compact pistols.
Can the battery on the SIG Sauer ROMEO-X Pro be changed without removing the optic?
Yes — the CR2032 cell in the SIG Sauer ROMEO-X Pro loads from the top, so the optic stays mounted and zero is retained.
What reticle does the SIG Sauer ROMEO-X Pro have?
The SIG Sauer ROMEO-X Pro uses the 2 MOA dot / 32 MOA circle (red) reticle.
