Questions & Answers
Will the Romeo1 fit a IWI Masada optics ready Expert Answer

The Sig Sauer Romeo 1 1x30mm Mini Reflex Sight has a proprietary footprint. So it will not fit an optics ready IWI Masada.

by Hunter, Gear Expert, April 5, 2022
Will this fit the p365x macro Expert Answer

The SIG SAUER Romeo 1 1x30mm Mini Reflex Sight is not compatiblr with the P365 X-Macro. This optic uses a proprietary footprint, larger than the optics the X-Macro is designed to accept. You can fit any optic with the RMSc or K footprint, such as the Sig Romeo Zero, Sig Romeo Zero Elite, Shield RMSc, Holosun 407K/507K, and Holosun EPS Carry.

Really nice product. by phil, June 22, 2017
Aquired one on a Sig 320 with it mounted. I still shoot Bullseye and this is as good, or better, as any red dot sight I've used in 28 years. Leupold, Ultradot, Aimpoint, Burris, any I've used. Adjustments track correctly. Virtually no distortion (th...

Good equipment, but some shortfalls by Coop, November 2, 2017
So I purchased this to put it on my P320 X5. It does come with a bunch of peripherals, which is cool. But the supplied screws are not the right size to attach the sight to Sig's own pistol. I called their customer service and they were aware of the p...

Product Info for SIG SAUER Romeo1 1x30mm Mini Reflex Sight, 3 MOA Dot

When you need fast and accurate target acquisition, the Sig Romeo1 Mini Waterproof 1x30 Reflex Sight maintains consistent zero shot after shot. TruHold twin adjustment springs provide a lock-less zeroing system that withstands punishing recoil. The compact size of these Red Dot Sights from SIG SAUER allows low and co-witness mounting. Each unit is CNC -machined from a solid billet of magnesium for lightweight strength. The Sig Romeo1 Mini Fogproof 1x30 Reflex Sight is equipped with MOTAC (Motion Activated Illumination) to power off when the unit isn't moving to save battery power, yet still remember your last brightness setting next time you turn it on. The molded aspherical lens of the Sig Romeo1 Lightweight 1x30 Mini Reflex Sight is bright and distortion free and the red-notch coating ensures a brilliant red dot.image
