It will depend on your pistol. There are 3 variants. If you pistol is not pre-cut for an optic, you would need an adapter plate. If your pistol is precut for an optic, it could be cut for one of two different sights, either the original Romeo1, or the newer Romeo1Pro (which shares a mounting pattern with the DeltaPoint Pro). If you do no know which one your pistol is pre-cut for, you would have to contact Sig directly, they should be able to tell you based on your serial number.

That depends on the style of rear sight your Rock Island 1911 has. If your 1911 has a novak style rear sight you can use MPN: SOR1MK007. If your 1911 has a G.I. style standard rear sight you will need MPN: SOR1MK006. If you have a target style rear sight like a BoMar or LPA, Sig does not offer a mounting plate for that style of rer sight.
None of these mounts fit on a SW9VE.
Yes, MPN: SOR1MK008 will fit.
No it does not. These adapter mounts are meant to replace the rear sight on the handguns listed and allows for the Romeo1 to be mounted to the adapter.
The Sig Romeo Zero Pro is designed to fit the P320 M18. Please email us at techsales@opticsplanet.com regarding your question.
These SIG SAUER Romeo Red Dot Mounting Kits are for the Romeo1 not the Romeo1Pro. We currently do not have an adapter to mount the Romeo1Pro to the Sig P365X Macro.
Unfortunately, the SIG SAUER Romeo Red Dot Mounting Kit is not compatible with your H&K-45 USP. We do not carry any adapter plates that would allow you to install the Romeo 1 on your pistol as the Romeo 1 uses a proprietary footprint limiting your mounting options.
The SIG SAUER Romeo Red Dot Mounting Kit will not work for mounting a Sig Romeo1 on a Sig M18. I recommend using the Romeo1Pro to fit the optics cut on that slide.
These SIG SAUER Romeo Red Dot Mounting Kits are for the Romeo1. They will not work for the RomeoZero.
