SIG SAUER ROMEO2 Kit Receives NSN Designation

NEWINGTON, N.H., (March 12, 2024) – SIG SAUER, Inc. is honored to announce the full ROMEO2 kit has been assigned a NATO Stock Number (NSN: 1240-01-717-4679) and officially placed on the MHS Additional Authorized List (AAL). This distinguished designation is part of the continued modernization efforts of the Modular Handgun System (MHS) Program and proliferation of SIG SAUER accessories designed and engineered to enhance the M17 and M18 platforms.

For inclusion on the MHS Additional Authorized List (AAL), the U.S. Army evaluated numerous pistol red dot sights, from multiple manufacturers, through vigorous environmental and performance evaluations and the ROMEO2 and the previously awarded ROMEO-M17 (NSN: 1240-01-713-9795) each achieved successful selection. The issuance of the NSN to these products streamlines the procurement process for all NATO members and partner countries as an identified standardized material.

The ROMEO2 is a Red Dot Reflex Sight that features a molded glass aspheric lens with high-performance coatings for superior light transmittance and zero distortion, available with a 3 MOA, 6 MOA, or Circle/Dot reticle, and offers D.A.R.C. (Dark Adaptive Reticles and Coatings) technology to provide ideal reticle brightness and target clarity during the day and while using a Gen3+ night vision device. MOTAC™ (motion-activated illumination system) automatically turns the optic off when not in use, and automatically turns it back on when it detects motion, and MAGNETAC™ (Magnetic Activation) automatically turns the optic off when holstered in a compatible holster, and on when drawn. The sight has a 7075-aluminum housing and comes with two (2) steel shrouds for three (3) different optic configurations, to include fully enclosed and sealed. A spring-loaded side battery tray with push-button release allows a battery change without the need to remove the optic from the firearm.

Additionally, the approved MHS AAL ROMEO2 kit includes Berry-compliant wrenches, an X-RAY3 green suppressor-height front night sight to co-witness with the integrated rear sight on the ROMEO2 housing, and a plug to fill the hole in the rear of the MHS slide when the sight plate is removed.

    What is the best WML light to hang on M18 ? Not concerned about the M17 and only want white light. I know Sig makes a light but don’t see them out on Sigs in the field.

      If it’s a duty pistol for field use, the answer is a Surefire X300 variant or Streamlight TLR-1 variant and call it a day. Both are proven in duty capacities. They provide more light than the compact lights that won’t extend past the barrel and the extra length doesn’t matter for a duty pistol. The one caveat is that you’ll need to make sure your holster can accommodate the light. Safariland will have you covered with an appropriate version.

      Modlite has incredible heads, but their pistol mounted body had issues with the switches and they weren’t very good at handling the issues with customers. As much as I like their rifle lights, I wouldn’t put one of their pistol lights on a duty pistol.

      If it’s a concealed carry pistol,
