Questions & Answers
Will this fit on a glock 45mos? If not, what is needed to make it fit? Expert Answer

The SIG SAUER ROMEO-X Pro is compatible with the Glock 45 MOS. To mount it, you will need to install the #4 MOS optic plate included with your Glock. Once installed on your slide, you will be able to mount this optic directly to the plate.

Will this fit the 320 x carry without a plate ? Expert Answer

Yes, the SIG SAUER ROMEO-X Pro uses the Deltapoint Pro footprint, meaning it will mount directly to your P320 without the need for an adapter plate.

Helpful Negative Review Good optic, bad footprint pattern by Nunya, Verified Owner, February 3, 2025
The optic itself is great. There are very few US assembled enclosed optics so I can appreciate this as an option. I tried mounting it on my G19 which has a DPP cut on it. The 4 recoil lugs were .1-.2 mm too large for the recesses in the optic. I tho...

Most Recent Reviews Excelent Optic by Rob, Verified Owner, September 1, 2025
I have this on a Sig 229. It has worked well so far. Did a 4 day pistol course with this optic and had no problems. It lines up perfect with the iron sights on the 229 Legion for a seamless alternate sight system.
Most Recent Reviews Clear dot low profile time will tell on durability by Rooster, Verified Owner, August 21, 2025
Like the optic- clear circle / dot and glass. Durability to be determined - let’s hope…
Most Recent Reviews Great addition to a Sig 226 Legion by Tom, Verified Owner, May 13, 2025
This is a great sealed sight that takes 5 min to install. It’s low profile with no adapter plate, so you save $100+ because you won’t need can sights. Go ahead and get the version that allows you to switch between circle and dot…unless you know you ...
