SIG SAUER – ROMEO-X Enclosed Series Red Dot Sights

Ever since SIG announced the ROMEO-M17 optic for the Modular Handgun System, customers have been asking for a version to fit their P320 pistols. During the recent SIG NEXT event in New Hampshire, they announced the ROMEO-X Enclosed series of red dot sights.

“The ROMEO-X Enclosed leverages our expertise as the industry leader in combining the durable optic technologies that are trusted by the U.S. military and armed forces around the world with a new standard in strength and reliability for the ultimate compact red dot,” said Andy York, President, SIG SAUER Electro-Optics.  “The ROMEO-X Enclosed has a fully enclosed, sealed, argon purged optical system, so it won’t fog, and has a low deck height so it easily co-witnesses with your standard-height iron sights.  This feature-rich red dot is inspired by the mil-spec ROMEO-M17 that delivers dependability without compromise, trusted by the military, and is the total solution for the most demanding shooters and circumstances.”

They is available in a compact version (ROMEO-X Enclosed COMPACT), to fit micro-compact pistols such as the P365, and a PRO version (ROMEO-X Enclosed PRO), to fit full-size pistols such as the P320.  It is also offered with three different reticles, a 3 MOA Dot, Circle Dot, and 6 MOA Dot.

You’ll note the low deck height for standard-height iron sight co-witness. Also, expect a minimum continuous runtime of 20,000 hours at medium brightness setting. This is partially thanks to their MOTAC™ (Motion Activated Illumination) and MAGNETAC™ (Magnetic Activation) technologies. 

According to SIG, the ROMEO-X Enclosed features a distortion-free aspheric glass lens, a patent-pending Beryllium Copper flexure-arm adjustment system, and a 7075 aircraft-grade aluminum housing with machined anti-reflection grooves on shooter facing surfaces.  The ROMEO-X Enclosed Series optics incorporate a high-efficiency point source red LED emitter available in either 3 MOA or 6 MOA dot, and also an available circle dot reticle, side independent brightness adjustment buttons, 15 brightness settings including night vision settings, and a side-mounted CR1632 battery compartment with a threaded battery cap so the optic does not need to be removed from the pistol for battery changes.  

The ROMEO-X Enclosed Series optics are now available at sigsauer.com.

    What if you have an older P365X/ XL slide that doest have a rear sight when you remove the plate?
    Hopefully they will make one with a built in rear sight.

      I have the Romeo xpro and it is cut with a rear site. But there is no dots it’s just A notch.

  2. WmW says:

    Are there any plans to release a variant for the P320-M17? I literally purchased my 320/17 after the announcement of the Romeo M17 in hope there would be a version for it.

      This exactly the optic a lot of us want/need.

    • RD says:

      Different optic for a different purpose.

      • WmW says:

        Fair enough.
        At this point though, I don’t really care what optic it is. I love the idea of the slide and the optic being designed specifically to work with each other. I really like that the M17 and the 320/17 have the cuts for the extra tabs on either the optic or mounting plates to index into. I like that this system sits the optic so low in an already tall (high bore axis) slide.
        If they became available, I would consider purchasing an M17 slide, but I am not aware of them being sold as a spare part.
        I’m just excited and want to give them my money for what looks like an awesome product.
