Questions & Answers
I currently have a Sig P320 X Carry and purchased a Romeo 1 pro. Do I need to buy a plate to mount it? Or it should be good to go? Expert Answer

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.

Which mounting kit do I need to mount the Romeo1 red dot sight to my Rock Island Armory 1911? Expert Answer

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.

Received the mount kit and installed on my sig 226. It was very simple to install. Removed the rear (hard sight), by driving the sight out using a punch and small hammer. Then slide the provided insert into the slot and then placed the base plate ...

Easy for a novice by David Gordon, Verified Owner, July 30, 2018
I purchased a Sig p320 and wanted a Romeo1 reflex red dot. I have never used a red dot in any form before. When I received the Romeo1 and mounting kit it took 10 minutes to determine how all the pieces fit but I can say in less than 5 minutes all p...

Romeo 1 Attachment Plate by James, November 4, 2018
The part came with no instructions...I had to just look at pictures on the internet and intuit the orientation of parts. It fits well, but is just the tiniest bit loose. However, that does not affect its holding the sight in place well on my Sig P320...

Great option for p320 by Gus, Verified Owner, December 10, 2019
I received this today installed in about 5 minutes. I didn’t snug the set screws because I’m waiting for my wheeler torque screwdriver to come in the mail. But it looks pretty bad I just hope that it holds zero .
