Sig Sauer Romeo Zero 1x24mm SpectraCoat Lens HD Lens Ultra-Compact Micro Reflex Sight

Awesome sight for my Shield Plus and P365. Its made of polymer and matches the stipiling on the P365. It comes with a metal cover or guard that gives you more durability and protection from a fall or everyday use. It's compact and fits subcompact pistols well and is ideal for concealed carry. Installation was easy for both pistols and I didn't have to modify or buy an adapter plate. It bolted right up and was easy to adjust. If you have a Sheild Plus or P365, this is the best sight for the money.

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

I highly recommend this product. This is a very good optic although the screen is not large the romeo zero works great and is very light and does not add appreciable weight to the 365 XL. The sight was easy to install set up and zero it has held zero. The dot does not wash out in good light but I have only used this at an indoor range. Under low light conditions it is excellent. The fit and finish of this sight matches my 365 XL perfectly, and if I did not install it myself I would have thought the 365 XL came with the sight from the factory. Time will tell if the Romeo zero is as robust as my RMRs which are great optics as I only have about 100 rounds with the Romeo zero on the 365 XL. I do agree that the on and off button is difficult to access if you have chubby fingers, maybe difficult even if your fingers aren't chubby. But the auto off (sleep mode) when the pistol is motionless and auto on when the firearm is picked up negates the reason to use the button. The 365 XL with the Romeo zero sight fits in my Desantis concealed carry holster I bought for use with the original iron sights. Positives: great fit and finish easy to install, easy to zero, holds zero, sight acquisition is faster than iron sights to get on target for follow-up shots. The romeo zero lengthens the effective range of the 365XL as the ability to acquire targets at distance is better and shots are more reproducible than with iron sights. Cons none with the auto sleep and auto on when picked up

The button to turn on and adjust this dot is in a dumb place that causes you to smudge the lens when pushing it. Changing the battery requires removing the sight. Adjustment for windage and elevation gives no feedback and the instructions don't give you much to go on when it comes to zeroing. The only good thing is that it's lightweight but that's because it's all plastic. Just save up for a better red dot
