Sig Sauer ROMEO1 1x30 mm Red Dot Sight - Durable Lightweight Waterproof Miniature Open Reflex Sight

Got this for my Sig Sauer P320 X Carry. On the X, you have to take the slide off, then undo screws to the removable plate (some additional cautions), unlike the Burris and Vortex. So had my armorer do it. When done, it does hang over the sides of the slide a little bit, but still is smaller than the Vortex. Didn't interfere with my hands racking the slide. I'd mounted a Trijicon HD XR on the front to help my old eyes with the iron sights. The Romeo's dot is able to size, and I like a medium size dot. Initially, aiming with red dot on top of the Trijicon, it shot about 4" low. Zeroed by aiming the red dot on top of the Trijicon, took 15 clicks, then 3 right clicks. Able to co-witness with Romeo's notch in the rear. Then, for rapid fire, visually shot by seeing dot in the center of the field, not using iron sights, and only slightly off center (emergency aim). On the X Carry, this works great. Tool included makes changing battery easy, (don't have to remove and re-zero) and adjusting if needed. Tiny added weight, gun still balanced. Really like this setup.

Now the price yeah it's pretty up there but if you want a nice handgun red dot it's pretty much up there with this one. But I like Sig sights this is like my 4th one, the brightness is easy to adjust, attaching it was new to me because this is my first handgun red dot, I have it on my Ruger 57 & honestly I like this one alot it had to be adjusted when I got it but that's normal. But it's very easy to sight it in. It's pretty accurate, a really good sight just kinda pricey

Great product

I don’t know how accurate it is. I couldn’t even get it on my sig M18. The screws it came with didn’t fit or something. They barely got tight as I was putting it on. Once it would get a little snug it would loosen as I’m turning it to the right. Then I realized that the threads on the screws stripped. Definitely was disappointed and did not even get to experience this product. Other than it being a paperweight or something that just takes up space

One less star because the flimsy cover that comes with the sight to protect it pops out if you look at it wrong, as a result, the metal around the glass now shows some scratches resulting from rubbing against barriers and targets moving around while the gun is holstered during USPSA matches, I can't use the cover because it will pop out and it will be lost.Sig should have used a rubber cover like other sight manufacturers.

Don't make the same mistake I did and assume your new Romeo 1 can mount on a newer generation P320 x compact. The x carry can have a Romeo 1 pro or Romeo 0 on it's slide, not the Romeo 1. The screws will not mount the optic despite appearing at first glance to be able to do so.Best of luck!

I recently purchased the Sig Sauer P320-M17 and figured i would put the Romeo sight on it. Ordered the Romeo1 here and got the 3 MOA version. Brand new in the box sealed. Installation was breeze once i figured out how to remove the extractor spring (YouTube to the rescue). Total install was about 15 minutes. Used my trusty laser bore sight and was range ready in less then 30 mins.Ran about 50 rounds though it seems to be holding Zero and was very fun to use. I set up Steel plates and shot form different ranges. Shot from standard stance the tried some draw from holstered. Did well fast easy acquisition. I think this will be one of my more fun to shot guns.

I've tried a number of red dot sights for both rifle and pistol and this sight is by far the best I've found for pistol. First unit being used on a Sig P320 X5 and it has transformed the gun as a shooting system - friends tried it and said "this gun shoots itself" it was so accurate.I like the clarity of the large window and the lack of distortion which was always a source of issue with the RMR. It has a built in co-witness rear sight to work with the existing front sight which is a bonus with the night sights. Dot sharpness is top of the range and brightness is adjustable for all lighting conditions. I will be buying more.This sight was easy to zero and has kept its zero.Don't hesitate - buy it.
