SIG Sauer ROMEO-X Sights

SIG Sauer ROMEO-X optics are open reflex pistol sights with a wide 1x24mm window and a switchable 2 MOA dot / 32 MOA circle-dot reticle. The ROMEO-X Pro uses the DeltaPoint Pro footprint, including the SIG P320, and the ROMEO-X Compact uses the RMSc / Holosun K footprint for P365-class carry pistols.

Frequently Asked Questions

What is a red dot sight?

A red dot sight is a non-magnifying optic that projects an illuminated aiming point onto a lens, allowing fast, both-eyes-open target acquisition.

How do I choose the right optic for my setup?

Consider your platform (pistol or rifle), the footprint/mount you need, reticle type and dot size, and whether you want an open reflex or enclosed design. Use the filters above to narrow by brand and specification.

Can I use a magnifier with these optics?

Many red dot and holographic sights pair with a dedicated magnifier mounted behind the optic. Check each product's compatibility details.
