Sig Romeo Zero Problems: Is Juliet The Only Solution?

While Sig makes great symbolism by naming their optics Romeo and the magnifier Juliet, unfortunately, Zero isn’t one of them that supports Juliet. Just like in real life, Romeo will die without love.

Jokes aside, just like the much more expensive Sig Romeo 5, there are quite a few Sig Romeo Zero Problems that you will need to be aware of. While some of them have solutions, a lot of them won’t. Read this completely before purchasing a Zero. Let’s jump right into it.

Sig Romeo Zero Problems

Sig Sauer RomeoZero 1x24mm Red Dot Durable Accurate Ultra-Compact Micro Open Reflex Handgun Sight for Concealed Carry & Slim Profile Pistols
  • SIG SAUER RED DOT SIGHT - The fastest, most accurate, ultra-compact micro reflex sight, the ROMEOZero 1x24mm pistol sight has been optimized for everyday concealed carry and pistols with slim slide profiles; Enables rapid target acquisition; Parallax free

The most common problem with the sight is the red dot itself. The red dot seems to appear at the paper left corner of the sight when you first activate it. If it happens to you, then you can easily fix it by zeroing it in contrast to your front sight. This way, you will always focus on the red dot instead of the front sight.

If you are suffering from a dim or low-intensity red dot, then you might want to change the battery. If your optic doesn’t get fixed even after changing the battery, then you will need to send it back to Sig to get it fixed.

No Rear Cover Plate Sight

If you are using the Sig P365XL for example, the rear cover plate with sight is not included. Another unfortunate thing is you cannot buy the rear plate cover separately either.

There is no fix for this and you are stuck with no rear cover plate.

The Button Placement

Most sights tend to have the brightness control button on the left or the right side of the optic to make it easier for you to press it and change the brightness on the fly. But Sig thought adding the brightness button inside the hood was a good idea.

Guess what? It wasn’t. You will often touch the lens from the inside while trying to change the brightness of the optic. It’s annoying and there is no fix for this either. Some 3D printed tools aid in this process, but it’s an eyesore.

The Build Quality

It’s not a surprise seeing the optic is not made out of aluminum. Rather, it’s made out of thermoplastic to keep the cost low and make it a viable option for the folks who are on a budget.

While the plastic is not that bad, it’s not the best either. It can break if you drop it from high places or smash it into a wall accidentally. While one might say for the price the build quality is acceptable, I would argue it should have had a better build.

The Glow Is Too Bright

Even if you put it at a lower setting, the sight seems to have zero effect on the Zero and not change the brightness at all! That’s an annoying issue and you cannot help but think you have a broken sight. And to some degree, you are correct.

If changing the battery doesn’t change your problem, then you are out of luck.

Should I Still Buy The Sig Romeo Zero?

Yes, you should. The Zero is an incredible value-for-the-money sight. While the build quality of this certainly could have been better, it could have been worse for the money as well. Sig isn’t charging an absurd amount for the optic either.

The lens quality on the optic is surprisingly great! It gets plenty of bright and the bright red dot does offer a good amount of visibility during low light as well. Perhaps a bit too much for some. That’s where your personal opinion comes in. You will need to decide if you are okay with a bright sight or not.


The Romeo Zero problems are quite low compared to Romeo 5 for example. For the price, the Zero did a lot of things right. Including the performance with compact carrying handguns.

While I would have loved to see an aluminum-made Zero, I can understand it will increase the price of production by a lot as well. It’s a strategic approach from Sig to make you buy their more expensive optics. And that’s how the market rolls, unfortunately.

Hopefully, this guide was able to answer all of your questions regarding the flaws of Sig Romeo Zero. With that said, that’s all for now and I will see you guys on the next one. Till then, take care and have fun!
