The Romeo 1 Pro might be just what you need whether you’re seeking an everyday carry (EDC) red dot or a red dot for the range. It offers some additional protection from sweat. And the smaller dot for longer-range shots can serve as a perspiration guard.
Its optic housing is made of aircraft-grade aluminum, which suggests that it was likely produced using the same material as your lower receiver.
Despite this, the SIG Romeo 1 Pro has some serious problems too. The most common issues with the SIG Romeo 1 Pro are MOTAC issues, poor battery life, poor brightness settings and vertical zero drifting issues
After reading this article, you will know the solution to all these problems. You will also know how the users feel about this product. So, stay tuned!

Common SIG Romeo 1 Pro Problems and Solutions

1. MOTAC Issues:
The Romeo 1’s MOTAC system (motion-detecting auto-on) does not work often. Regardless of what you do, you can’t get it to switch on by itself.
The optic can be turned on or off with the up or down button, however, it may not come back on when moved. For the next few minutes, all you have to do is hit the button again.
The Fix:
The first thing to do is to call SIG obviously. However, if they cannot find any problem (let alone solutions), I can teach you a few tricks up my sleeve.
For the first time, you’ll have to use the buttons to turn it on. Once it senses no movement for a few minutes, the dot will turn itself off to conserve battery power (power saving mode). It will turn back on if you move it once more.
Even after getting fixed by SIG, the extraction continues to be feeble. However, after a few hundred more rounds, it will get better.
2. Poor Battery Life:
First of all, the MOTAC feature is very sensitive. Just walking is enough movement to keep it on. So, you will probably go through a lot of batteries. Additionally, the battery cap comes loose quite often.
Suddenly, the Red DOT may fail to function. It works for a while if tinkered but then goes out for good. After a few rounds the buttons would stop functioning too.
SIG apparently ensures the stock battery life is just 2-3 weeks. For an SD gun, this is not acceptable.
The Fix:
For the battery issue, you can do nothing but to replace the batteries. However, a better alternative is replacing Romeo 1. Anything with a battery is not good for self-defense.
They are not as developed as say, like an Eotech or an Aimpoint.
3. Poor Brightness Settings:
It’s tough to use the brightness buttons on the side of the sight with large hands. You can’t tell if the sight is on or off because the on/off switch is located on the same button. Each MOA adjustment does not produce any click sounds.
The brightness settings are either too high or too low. You can tap it with a metal object and get a nick in it easily.
The Fix:
Send it to SIG. They have a killer warranty on it and they will fix it. You can also try a new Duracell battery before sending it to SIG. In terms of the inaccessibility of buttons, it’s a design issue and you can rarely do something about it.
4. Vertical Zero Drifting Issues:
The vertical zero is prone to severe drift. It appears like Sig made an effort to fix the vertical drift issues with the Romeo 1 Pro’s “TruHold” zeroing technology. But that may have made things worse.
You won’t be able to zero the rifle by adjusting the vertical zero far enough. At maximum vertical elevation, the cannon will be 1.5 to 2 inches low at a range of around 15 yards.
The Fix:
You need to return the R1 to SIG. The technician will discover if there’s a problem with the vertical adjustment mechanism. It may then require some shimming.
A feeler gauge can be used to produce a shim; simply trim it down to size with a pair of tin snips.
User Feedback on SIG Romeo 1 Pro
The MOTAC shake awake feature consistently performs as intended. It might, however, frequently turn off when being worn in the holster. and might not turn back on reliably during the draw.
However, as it meets USPSA requirements, it is acceptable for carry. The Romeo 1 is also suitable for official use. On some weaponry, you might require an additional shield, though.
Popular mounting options for Romeo 1 include P320 X-Carry, P320 X5, and CZs. People would personally choose the PRO over any other option available, including Trijicon. Although the battery life is excellent, it must be changed every six months.
The kit also includes a plastic cover in addition to the steel shroud. If you tried to carry the rifle while wearing the cover, it would be easy to lose it. However, the plastic cover is ideal for storage and transportation.
I came across multiple owners that suggested the 6MOA dot for pistols instead of the 3MOA dot. I believe it comes down to personal preference and how you plan to utilize the site.
The dot is clear and simple to acquire in the sight with a slight adjustment of brightness. Especially surrounding lighting circumstances. Overall, an excellent sight at an excellent cost.
Frequently Asked Questions (FAQs)
When you zero the Romeo 1 Pro, do the windage and elevation get reversed?
You turn the elevation in a downward direction to lower the point of impact. Windage follows the same logic as well.
Can the Romeo 1 Pro be installed without the shroud but still using the two screws that come with it?
Yes. Just get shorter screws or cut the ones you have.
How to know if a factory Romeo 1 is 3 or 6 MOA?
A 3 MOA reticle will look like a 3-inch circle on the target while a 6 MOA reticle will look like a 6-inch circle on the target. Moreover, some guns especially ship 3 or 6 MOA guns only, so try to find that information.
Conclusion
I will start with a generic advice: Don’t go cheap on your optics. If you choose a cheap option, you will eventually have to buy another when the cheap one fails. And you may also face trouble in a critical shooting situation.
Being said that, the Romeo 1 although cheap, has been quite reliable. It withstands being struck, jammed, and rolled over concrete. An additional layer of protection surrounding the optic is provided by the redesigned shroud.
Direct bolt-on installation takes only a few minutes. It is also a direct fit for the cutout on guns like the P320-M18. But you should know that it doesn’t fit a lot of the older SIGs.
All things concerned, the SIG Romeo Pro is a good option for an optic!
