The SIG Sauer ROMEO-X Pro Red Dot Sight in this listing is the 3 MOA dot version — a 1x (non-magnified) open-reflex pistol red dot sight on the DeltaPoint Pro footprint, with a 24 mm aperture and a top-loading CR2032 tray.
A single 3 MOA dot is the middle choice in the ROMEO-X Pro range: finer than the 6 MOA dot for precise work, but still quick to find under speed, and without the circle that the 2 MOA / 32 MOA circle-dot model projects. It runs 15 brightness settings, three of them night-vision, with MOTAC motion activation.
Compatibility
DeltaPoint Pro (DPP) footprint — fits DPP-cut slides and optics-ready pistols with a DPP plate. Confirm your slide cut or plate before ordering.
How It Compares
Want a larger dot for speed? The ROMEO-X Pro 6 MOA is the alternative. Want a selectable circle-dot? See the ROMEO-X Pro 2 MOA / 32 MOA. Prefer green? The ROMEO-X Pro 3 MOA green projects the same dot in green. Carrying a slimmer pistol? The ROMEO-X Compact uses the RMSc footprint. Browse the SIG ROMEO range and all optics for optics-ready pistols.
Ideal For
- Optics-ready pistols with a DeltaPoint Pro slide cut
- Airsoft, training and licensed pistol setups
- Pistol-calibre carbines and long-barrelled pistols

Frequently Asked Questions
What reticle does this SIG Sauer ROMEO-X Pro have?
This SIG Sauer ROMEO-X Pro uses a single 3 MOA red dot, with no surrounding circle.
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.
Should I choose the 3 MOA or the 6 MOA SIG Sauer ROMEO-X Pro?
The 3 MOA dot on this SIG Sauer ROMEO-X Pro covers less of the target for precise shooting, while the 6 MOA version is larger and quicker to pick up at speed.
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.
Is the SIG Sauer ROMEO-X Pro night-vision compatible?
Yes — the SIG Sauer ROMEO-X Pro has 15 brightness settings, three of which are night-vision settings.
