Hello i have a Carry 9 DS and was looking for confirmation on an optic i have a sig Romeo zero as of now and it’s scratched and dim so I’m looking for a new optic I have been reading and some forums/websites say these will fit the HS/K pattern as from what i can see is just a different form of rmsc and then some don’t so i was just wondering if anyone has a k footprint optic on there’s or if thats even worth it and instead just get a plate for rmr footprint if that is even a thing? Any help with this topic would be appreciated.

Does anyone have a traceable outline of this album that i could possibly copy for a project or know a way of obtaining something that would work as i’m not very artsy? Any help would be appreciated. 🙏
