    • One of the Best Optics I've Used!
Color: Black Style: 2 MOA / 32 MOA Red Circle Dot
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. ... show more

    • Worth the money
Color: Flat Dark Earth Style: 2 MOA / 32 MOA Red Circle Dot
Another great Sig Romeo Optic for my P2320-M17. It's the top of the line and pricy, but only the pro series would mount on my slide without a mounting plate. Had I gone with a cheaper option the mounting plate would have made those options cost more. I own 3 other Romeo Optics, and love them all. They are rugged, accurate and hold zero. ... show more

    • Great optic but make sure you don't have an astigmatism before ordering
Color: Black Style: 6 MOA Green Dot
Nice sight with good fit but the dot was blurry so I had to return it.

    • Only lasted 30 rounds of 9mm
Color: Flat Dark Earth Style: 2 MOA / 32 MOA Red Circle Dot
Only lasted 30 rounds of 9mm. After I zeroed it I started noticing about 10 rounds later my shot groupings were all over the place, and then finally the reticle disappeared while I could clearly see the laser was still on. I only bought this once so it could’ve been just bad luck but given its a $500 optic I’d expect quality control to have caught something like that. ... show more
