Next Revolution in Red Dot Optics

Sig Sauer has officially launched the ROMEO-M17 red dot sight that was seen at SHOT Show 2023. The sight was originally developed in part with the Army’s Modular Handgun System and is designed specifically to fit the MHS M17/M18 pistols, M17/M18 Commemorative Special Editions, and M17/M18 Surplus pistols.

“The fully sealed ROMEO-M17 is the next revolution in red dot optics; it answers the call to withstand the rigors of the battlefield and works seamlessly with the U.S. Army’s Modular Handgun System,” said Andy York, President, Sig Sauer Electro-Optics.

“The ROMEO-M17 is the first red dot sight to incorporate SIG SAUER’s patent pending SIG-LOC mounting system. SIG-LOC (Leveraged Optimized Connection) features a new proprietary bottom-mount technology that has multiple interface features between the pistol slide and the optic that provides for an extremely strong and robust lock-up. This new mounting system, when combined with the side mounted battery on the ROMEO-M17, allows the optic to have an extremely low position when mounted to the slide, giving the user a full sight picture and co-witness with the existing standard-height iron sights. This sight was engineered, tested, and built in Oregon to be the ultimate aiming solution for the MHS pistols.”

Fully Enclosed

The Mil-Spec electro-optics ROMEO-17 is a fully enclosed system that has been sealed and gas-purged. The 7075 Aluminum housing is machined with anti-reflection grooves to keep down glare, and it contains an integrated gas deflector in the front end. With the system being fully enclosed, Sig states the optic has ultimate protection from the elements.

Mounting

The ROMEO-M17 mounts differently than any other optic on the market. Thanks to the special cuts in the slide, the ROMEO-M17 mounts from the underside of the slide and is held in place with screws. This allows the optic to sit extremely low on the slide for easy co-witness with the standard height sights. At the present, the ROMEO-M17 is not compatible with the standard P320 or P320-M17/M18 slides, but Sig states those compatible slides will be coming soon.

Function

The optic itself is a high-efficiency point source red LED emitter with a 2 MOA dot/32MOA circle reticle. Independent brightness adjustment buttons on the exterior of the housing have tactile bumps, making them accessible to the user even when wearing gloves. Of the 15 brightness levels to choose from, three are optimized for use with Gen 3+ night vision devices. The side-mounted CR2032 battery compartment allows for changing out the battery without removing the optic.

“The ROMEO-M17 is the pinnacle of pistol-mounted red dot optics, and we are immensely proud that it has been tested and selected to receive a NATO Stock Number (NSN) from the U.S. Army so this innovative technology and ruggedized performance is easily attainable and available to our warfighters,” concluded York.

The Sig Sauer Electro-Optics ROMEO-M17 is fully assembled in the USA and has an MSRP you’d expect from Sig at $809.99.
