Review: Quality Sight - I have been a Gunsmith for 44 years and have mounted more RMR type sights than I can remember. The Sig ROMEOzero was very straight forward in its mounting. It was mounted on a Glock 27, .40 S&W utilizing a dovetail mounting plate. The majority of these sights are metal but the ROMEOzero is a polymer housing. This particular mounting was for my personal EDC firearm and I can honestly say I have mounted more different brands than I can remember. I chose the Sig because I wanted a sight that was small but still presented an excellent sight picture. The instructions from Sig were well written and would serve a shooter who has never mounted this type of sight. Of note and great importance is the warning of not to over tighten he mounting screws because it could deform the polymer and cause the sight to malfunction. My first observations were the automatic waking of the sight with the slightest movement. Yes, this is going to cause the sight to be on with the daily movements but off whenever the firearm is still. The presentation of the red dot is very impressive when bringing the firearm up to the shooting position. I found that I needed to bring the intensity of the red dot down to mid level of brightness. Doing so gave excellent presentation in bright sunlight as well as total darkness. I urge the shooter to experiment with this to find what works best for them. Range time revealed the need for sight adjustment. Shooting at a 7 yard distance I fount he elevation to be perfect but I did need to adjust windage to the right. The adjustment screws are well defined with arrows indicating direction of travel. They are also pronounced with a solid felt click for each moment of travel. After adjustments over 50 rounds were fired with the sight holding perfectly. All screws were checked for problems and none found. I am also an NRA pistol instructor and Training Counselor and would urge anyone to consider this sight or one like it for defensive shooting. It gives the shooter faster sight acquisition and far better grouping than standard “iron sights”. Lastly I paid for this and have not been compensated in any way. Be SAFE…..Shoot WELL
Review: Great transaction. - Awesome quality! Beyond pleased.

## Questions & Answers

**Q: Does this come with mounting screws?**
A: Yes, I mounted it on a Glock 48 using the shorter set of screws.  I had to shave the right hand screw so it did not cause issues with the operation of the pistol.  There are serval good videos on this procedure from start to finish.

**Q: Is this only compatible with Sig or can be installed on other firearms?**
A: The Romeo 0 uses the "shield" mounting footprint. It won't mount on everything milled for a red dot. You must verify that the firearm accepts the ability to mount this style footprint.

**Q: Is there a way for this to mount to the p365 sas slide after removing the built in sight system?**
A: Yes. You can purchase an adapter from Nameless Armament.  The adapter fits inside of the frame when the SAS sight is removed.

**Q: What mounting plate or screws are needed for the  glock g43x mos?**
A: Everything you need comes with the romeo zero. No plates needed.

### ⭐⭐⭐⭐⭐ Excellent Dot
*by T***5 on December 14, 2025*

I was suprised by how sharp and clear this dot it. VERY bright. Only have a few hundred rounds with it attached but has held zero and worked perfectly so far. Auto sleep/awake makes it very easy to use. Got it on sale but worth it even at full price.
