P226 Frame Width?

[Rudukai13]

I'm looking for some help from a P226 shooter - Specifically, I was hoping someone could measure the frame thickness at the dust cover, just above the rail.

I'm trying to determine the best way to add an optic frame-mount, and I know there are different mounts for 2011s that vary based on the frame width of the 2011. I'm thinking if I can find a mount that's meant for a 2011 with a similar frame width as the P226, I could adapt one of the 2011 mounts to fit the P226 frame. Of course if there isn't any manufactured mount that would work, I can always go the custom route, but was thinking it'd be helpful to at least look at a pre-manufactured mount first.

Thanks in advance for any and all help!
