SIG SAUER Electro-Optics Introduces the Next Revolution in Red-Dot Optics: THE ROMEO-M17

NEWINGTON, N.H., (April 14, 2023) – SIG SAUER Electro-Optics is proud to introduce the ROMEO-M17 pistol mounted red dot sight.  Developed from the ground up for the U.S. Army’s Modular Handgun System to be the ultimate in performance, reliability and durability.  The ROMEO-M17 is designed specifically to fit U.S. Military Modular Handgun System M17/M18 pistols, M17/M18 Commemorative Special Editions and M17/M18 Surplus pistols with a single hole in the slide to secure the sight plate.  It does not fit standard P320 or commercial P320-M17/M18 slides.  Commercial variations of compatible pistols and slides will be available in the coming months. 

“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.”

The SIG SAUER Electro-Optics ROMEO-M17 is a mil-spec, fully enclosed and gas-purged red dot reflex sight with a distortion-free glass aspheric lens, and is submersible to depths up to 35 meters.  Other features include a new and very robust flexure-arm adjustment system made of the same Beryllium Copper found in many riflescope designs, and a housing that is forged and machined from 7075 Aluminum with an integrated loaded chamber indicator (LCI) gas deflector and machined anti-reflection grooves on all rear facing surfaces for reduced glare.  The optic incorporates a high-efficiency point source red LED emitter, with 2 MOA dot/32 MOA circle reticle, independent brightness adjustment buttons, 15 brightness settings including night vision settings, and a side-mounted CR2032 battery compartment with a threaded battery cap so the optic does not need to be removed from the pistol for battery changes.  The ROMEO-M17 has a minimum continuous runtime of 50,000 hours at medium brightness setting, and utilizes MOTAC™ (Motion Activated Illumination), MAGNETAC™ (Magnetic Activation), and D.A.R.C™ (Dark Adaptive Reticles & Coatings) technologies. 

“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.

    So the M-17/18 pistols sold in the BX are different from the issue weapons? Interesting.
