Vang Comp rear sight for 590A1 installation

Hello hope all is well,

I have a question, has anyone ever installed one of these on a 590A1 that was pre-tapped from the factory? What was your experience with it? I know it is doable, I was also wondering how different the hole pattern is?

Thanks sorry for the noob question I am new and couldn't find any information on this. I look forward to learning lots here.
 
I work for Vang Comp. We've installed our sights on NUMEROUS 590s.
The predrilled & tapped holes on the receiver do not line up with the screw holes in our sight however.
