Style: 3 MOA Red Dot
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

Got this to put on a Sig P365XL and so far happy. Battery replacement will be a slight pain since you will need to remove the slide, then unscrew the optic to get to the battery location. The MOTAC feature is nice but I would have liked the auto bright/dim feature but for the money Im not going to complain. The dimmer button is sort of an odd place but I use the medium brightness settings so its good enough for day but not too bright at night. MOTAC Auto On/Off feature seems to work very well but is very sensitive to movement. Just touching the firearm will auto on. As for battery life, time will tell. What the description doesnt say is while yes its a polymer frame, it does also include a metal frame that the red dot will slide into before mounting then mounts all as 1 piece. So it does give some more added protection. Whats also nice is unless you look very close you cant tell its there. Each side of the metal frame does have Sigs logo. It also doesnt really add any weight thats noticeable either.

Like several other mini red dot systems, the battery is inserted in the open underside of the sight itself. I installed on an Sig P322 thinking that this would be a good fit for the light recoiling of the .22lr pistol from the same manufacturer. Problem I had with this is the plastic body flexed when I torqued the screws down to the recommended 9-inch/pounds. It caused the sight body to lift in the front just enough the battery contacts wasn’t enough to run the red dot. It worked when I first put in the battery manually holding in place and checked the functionality. After I uninstalled, again verified the sight worked by holding the battery in place manually, reinstalled the sight to only have it not work again. I backed off the screws rough that noticed the sight slightly dip down in the front of the sight body. I tried dry firing the pistol and got the light to blink on and off as quickly as it came on. The sight overall seemed to be nice and I liked the fact it fit the pistol without having to get a plate to adapt it. I liked the pebbled texture along the side of the sight body that closely matched the grip texturing. Maybe I got a more flexible housing than what it should be but I’m sending this back. Spend a little more money for a Holosun 507K. I have one that’s proven on my G43X.

Awesome little red dot! It's the perfect size to continue using my P365X as my EDC without digging into my skin. It comes with a protective steel "cage" which overall doesn't add too much of an increase in size while giving me not only piece of mind for bumps and bangs, but allows for a more secure purchase on the slide. The cage does hang off the edges on the slide, but it's such a small amount that it doesn't create issue. The sight also has a built in rear sight so you can have a backup standard sight in conjunction with the front sight, in case your battery dies. Adjustment is simple and easily achieved. There is a rubberized button towards the inside of the glass that allows you to adjust the brightness to 8 different settings, or press and hold for 2 seconds to turn off the motion activation. Pros: -Easy to install -Feels sturdy -Allows for better purchase on slide -Motion activated -Built in rear sight for backup -Simple to adjust MOA and brightness -Still allows for concealed carry -Looks good Cons: -Have to remove sight from slide to change battery -Have to recenter dot after every battery change -Hangs off the edge of slide with or without protective "cage" -Have to purchase specific button cell batteries every now and then (wish it was rechargeable so I could just plug it in after my weekly clean) Overall: Awesome little red dot that enables an easier sight picture without compromising EDC capabilities. Super simple and straight forward installation and operation. Great quality for the price. If you're in the market for a micro red dot for your SIG, look no further!

I put this on a S&W M&P Shield 9 EZ and have used it for 3 months now. It required a separate dove-tail plate adapter (not included here, in fact not even found on Amazon last time I checked). If you didn't know, you need to zero any sight you buy. Do not trust it to be perfectly zeroed from the factory. Mine was waaaay off out-of-box. The windage and elevation screws can be tight at times, so gently use the included hex tool to adjust. I was able to significantly scratch the inside where you look through, the view-port, within a couple days. I don't know from what, I don't blame the product - but just know that it's NOT scratch proof. Surprising the more exposed side, the side you don't look through, is unscratched after 3 months. The view-port also gets easily smudged with dust and oil. Cleaning it requires a soft-cloth and a thin tool in order to reach the edges with the cloth. The button to adjust brightness is NOT easily accessible. It is horribly deep near the actual view-port glass, and you have to press it pretty hard to cycle the brightness. I wish the button was on the sides or back. The red dot itself has perfect low to high brightness, no issue there. It claims to have "motion-detection" which I have observed is true, but sometimes it doesn't turn off as expected. I've put my firearm down on a table for a day, and came back to see that the red dot was still on. I've also observed that the dot does turn off after awhile. So it just seems to be finnicky. Installation was simple. Comes with various screws. Overall decent purchase, does its job, but pretty pricey when it has a handful of issues. 3 stars because of this. Would be 4 stars if it wasn't so expensive, because it's still very functional even with my issues. Edit after 6 months of use: The motion-detection feature seems to completely not work. Perhaps it's detecting the miniscule motions of the Earth, because it just doesn't seem to turn off when inactive. I've put it down in multiple different locations of my house, and the dot stays on several hours after. The battery has already died after 6 months, so I'll need to throw the irons on until I can pickup a new battery. Disappointing, as the motion-detection was the most important feature I wanted.

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
