Thank you sir, that is very helpful.
I'm not so much worried about holster fitment with the sights as I am having an unreasonable height over bore situation. It looks like the sight heights come in somewhere between a direct milled Glock and a MOS Glock, but is closer to the direct milled.
Your comment about not feeling like it was too high is really what I'm looking for. I know that is obviously subjective, but its good to know that it has a good feel.
Does the adapter plate extend the entire width of the optic so that a sealing plate isn't needed? It looks like it would be, but it's hard to tell from pictures.
