Questions & Answers
What’s the difference between the “Pro” and “Elite”? Sig makes no mention of this sight on its website.

From my understanding the elite is for smaller pistols ex: p365/365xl and the pro is for full size pistols ex: p320 series.

by Johnathon, Verified Owner, May 20, 2022
What footprint? This should be very easy to find info for any red dot but for some reason it's not. Is it rms/rmsc like the smaller Romeo zero? Expert Answer

The Sig Sauer Romeo Zero Pro uses the Leupold DeltaPoint Pro optic footprint and fits compact/full size handguns like the P320. The Romeo Zero Elite uses the Shield RMSc optic footprint and fits micro handguns like the P365XL.

Helpful Positive Review Red dot for the Sig 320 M18 by JoeB, Verified Owner, May 10, 2024
Great red dot sight that actually fits the M18 without an adapter and doesn’t cost as much as the pistol itself. Direct fit, wakes up on movement, easy to adjust and stays on zero. I didn’t use the metal shield because I don’t plan on using it as a b...

Helpful Negative Review Durable as tissue paper by woody, August 26, 2023
I would not recommend this for your EDC. Cheap plastic body and lens, easily scratched and is a lint magnet. The button is in the worst place imaginable and impossible to use without leaving a fingerprint on the underside of the lens. The whole sight...

Most Recent Reviews horrible product by Rodney Klein, Verified Owner, January 1, 2024
Bought it on the suggestion of Sigg. Thought it would be awesome. Unfortunately it is not. The control to turn everything on, off, brightness, everything is all in one button. And the button is right in front of the screen. It makes absolutely no sen...

Most Recent Reviews Adjusting the brightness is nearly impossible on the fly. by MattB4D, October 22, 2022
Positives: Having multiple reticles is a nice feature and it does sit nice and low if direct mounted and can 1/3 co-witness with my tall sights on a P320 X-five Vtac. Negatives: You have to manually hold a tiny button near the lens to activate the b...

Product Info for SIG SAUER ROMEOZero Pro Red Dot Sight

The ROMEOZero-PRO brings the lightweight polymer design of our ROMEOZero line of micro reflex optics to a full-size pistol optic built with a host of premium features. The ROMEOZero-PRO model is compatible with all SIG SAUER ROMEO1 PRO optics-ready pistols. This new full-size reflex optic features a large 30mm aspherical lens made of scratch-resistant glass, offering unmatched clarity and a distortion-free sight picture when compared to competitors. The ROMEOZero-PRO features a proprietary carbon-infused polymer housing with a reinforced lens protection area making it incredibly durable while delivering significant drop and impact protection. It also comes with a hardened steel protective shroud for even greater protection and durability. The ROMEOZero-PRO is available with either a 10 MOA red dot or the versatile new circle/dot reticle. The new T.A.P. (Touch-Activated Programming) technology gives the user the ability to change brightness with just a tap on the optic. All rear surfaces of the housing have anti-reflection grooves molded in, including the backup rear sight notch which is marked with Grade A Swiss SuperLuminova pigment for visibility in dark environments.image
