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.

Hidden value …low profile by Tom, Verified Owner, May 6, 2025

Romeo X-Pro by jdeere509, Verified Owner, February 19, 2025

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...

Great Optic by Big-A-Rob, Verified Owner, January 29, 2026
I have really come to like the reticle on this optic. The build quality is up there with the top manufacturers. I really love how low the deck height is and the width is within most slide widths without any overhang.

great optic by DT, Verified Owner, January 29, 2026
Solid build. USA made, trusted over holosun (has issues with 407k x2). Enclosed emitter is great technology.

Doesn't fit Staccato HOST DPP plate by RC, Verified Owner, January 22, 2026
Seems like a nice optic but beware as it does not fit the Staccato HOST optic mount plate for DPP. The bosses on the plate are too large for the pockets in the optic. The optic does however fit on the Bul Armory BAO plate for DPP.
