Most Helpful Positive Review Really nice product.

Aquired one on a Sig 320 with it mounted. I still shoot Bullseye and this is as good, or better, as any red dot sight I've used in 28 years. Leupold, Ultradot, Aimpoint, Burris, any I've used. Adjustments track correctly. Virtually no distortion (that I can see)! Great price point with a 10% discou...

Most Helpful Negative Review Battery life

After two sessions of 200 rounds the sight has turned off. I've changed the batteries, and tightened down the cap. Nothing. This is very disappointing being that I'm a huge fan if sig. Anyone having the same issue?

Romeo 1 review

by Gill, Verified Owner from MA, United States Written on May 31, 2026

I purchased this site because it’s the only one that will fit my 5X6 SigSaur. It’s an older version and has the flat side cut towards the front of the muzzle. So this is the only site designed to fit that spot unless you get an aftermarket adapter plate. I had no trouble putting the site on directions were very good. It’s easy to operate and the 3MOA red dot is extremely bright in any light. The only disappointment was the advertisement from Sigg said that it would awake by shaking the weapon and it does not seem to do that. Since this is just a target pistol for me, that’s not as important as a precise dot and an easy to acquire image overall I’m very happy with the site except for the fact that it does not shake awake like the sigsauer ad states

Screws don't fit the P226 it was meant for and didn't come with tool to zero in

by Whiskey Diet, Verified Owner from CA, United States Written on September 25, 2025

Don't waste your money. The Romeo1 does not fit into the Sig Sauer P226 Optic Cut Slide. I thought it was just the screws that came with the red dot (which came off after shooting 3 rounds)

I then ordered replacement screws and a new tool for this (Spent another $34 bucks) and the screws Sig sent me won't work on this either or fit into the optic cut.

Pros:

None

Cons:

Doesn't fit into the Sig P226 Xtreme Optic Cut SLide

Sig Romeo optic

by Jonathan Merced, Verified Owner from NC, United States Written on August 1, 2023

This is not my first Sig optic nor will it be my last. Sig optics have not disappointed yet and recommend them to anyone who is looking for a reliable and decently priced optic. Easy to install but I do wish the installation screws weren’t as delicate.

Great for the price.

by Nick B, from FL, United States Written on May 2, 2023

First off. This is a demo item so it didn’t come with all of the features and attachments that would normally be on the product. This I understand, but the batteries that it came with were dead out of the box. Had to buy new ones. Other than that, the condition it was in at delivery was superb. That’s worth the 4th star

Pros:

Great condition

Cons:

Parts not included
batteries came dead

My favorite reflex sight!

by Old eyes shooter, from OK, United States Written on June 30, 2022

This is my third Romeo 1. They work great and I trust them. Using on my Glocks an S&W. Easy to adjust and holds it’s zero. Battery easy to install. Very durable too! It’s a bit expensive but worth it. BE CAREFUL OF WEB SITES OFFERING A REALLY GOOD DEAL, I almost got taken on a $200 deal.

Lost screw

by Shheller, from IN, United States Written on December 29, 2021

My boyfriend was happy to receive this for Christmas. He placed it on his handgun and went out to test it. After 5 rounds the whole thing came off. He was able to find screws that fit and went out and tried it again and after testing it out again it stayed on but became loosened after 3 mags through it.

Pros:

easy to adjust red dot

Cons:

screws loosened up

Disappointed

by Reagan Gregorio, from IL, United States Written on August 16, 2021

I do not recommend this red dot sight. I have to change batteries in 24 hours, twice! The manual clearly states that it will auto-off itself if dormant for two minutes and will auto-on when moved. After keeping my sig P320 safely after doing some dry firing, the batteries simply drained out the next morning. I’m utterly disappointed! That’s why we need also to train with iron sights, just in case.

Hardware too short

by AeolianX, Verified Owner from MO, United States Written on August 11, 2021

The screws that come with this red dot are too short, even for Sig handguns. You get one or two threads, and if not careful, you'll strip them out. It's a great red dot otherwise. I bought this for a Sig P320 compact, and this was my issue. Now I get to find the correct length mounting screws.

Pros:

quality red dot

Cons:

Crappy Hardware
