Sig SauerRomeo-X PRO Pistol-Mounted Red Dot Sight - Durable Aluminum Lightweight Waterproof MOTAC Miniature Open Reflex Sight with 15 Illumination Settings

The Sig Optics are usually always pricey but the quality one gets for the money is worth it. I purchased this Romeo X Pro to use on my service pistol, a Sig P320 X Full size. I work professional armed security and I wanted an optic that would ensure optimum accuracy if a situation arose that requires me to deploy my firearm in defense of the workers I protect. The Romeo X Pro has given me that confidence. I was able to install the unit on my P320 in less than 15 minutes. Since Sig has upgraded to the X frame system, the Romeo X Pro dropped right into place after removing the optics plate. The optic is made to co-witness with the pistols existing sights. My only difficulty was understanding the zeroing directions properly in the Sig optic manual. But after some adjusting and sighting in shots I got it zeroed to excellent accuracy. The optic's controls function easily, though I used the factory setting with the circular reticle with the dot inside. Brightness is easily adjusted with the side buttons. It turns on and off easily ensuring maximum battery life. The battery is easily accessible. I have had no problem at all with it and I practice weekly at an indoor range. I am pleased with it's continued accuracy every time I shoot. I own a number of Sig Sauer pistols and have Romeo Pro optics on my P229/M11A1 and my P320 M18. I also use a Romeo Zero Elite on my P365 X TACOPS which is my EDC. All of the Sig optics are top notch in quality and accuracy and durability.

Fits perfectly and looks nice. Going to the range today to try it out

Prefer this over my Holosun 507 for a variety of reasons. It sits low to the frame, so you don’t need higher sights to co-witness, so factor that into your costs. The glass is clear and sharp. Dot and circle are just the right size. Has shake awake so the light turns off then instantly on when it detects movement. Has a built-in sensor that deactivates the light while the gun is holstered if you have a magnet in your holster. Has held zero after 150 rounds through my 10mm. The battery access on the side is funky, but it’s the easiest to change on any red dot that I’ve encountered. It bolts directly to a P320 without any issues - less than a 5 minute install. I like this much, much better than the Romeo 1 Pro as well.Important note: Amazon is jumbling these up! There are two versions: One for a full sized pistol (P320) and one for the micro pistol (P365). Make sure you get the right size!

I originally said that this sight has a "Very small window compared to the Trijicon SRO and Holosun 507 Comp." After using this sight for a while, however, I've completely changed my overall opinion - despite the smaller window, the large circle around the red dot makes target acquisition much easier and quicker than a single dot. I prefer this optic to either the Trijicon or the Holosun. Also, the sight sits low enough on a SIG P320 to co-witness with the existing iron sights and has a very easy to access battery compartment that does not need a special tool!

Best red dot optic I’ve ever owned by far! It’s sits low so you can use regular height sights, and holds zero. The dot is very easy to see. And it seems durable.

Awesome sight! Easy to install and zero. Great addition to my Legion X5.

Lately Amazon has been slow, not with seller two days morning delivery. Product is exactly as advertised. I would include a picture with it mounted except the parts I am going to mount it on haven't arrived. Expect them on Monday five days later than to optic. I will order for them again. Just waiting for the enclosed version to be released. Price is better than who I normally buy from and shipping is so much faster.

Not worth 500 bucks almost. I would rather just keep using an iron sight
