Go to the SupeTuck order page and you can select an option for optics, with or without tall sights. They do show Ruger Max 9 as available.I was looking at the supertuck and that made the short list but it just looked so huge and wouldn't take a red dot on the pistol.
Also, any hybrid will look large to you, compared to simpler single or double clip kydex holders. The added width of the leather back does add to the comfort when wearing.
[dang auto-corrupt keeps changing kydex to index!]
