I quizzed two manufactures about making a simple 3 - 9, both almost verbatim said, magnification sells.
Blame your fellow shooter, market driven environment, they build what sells.
What's wrong with a Trijicon Accupoint 3-9x40 with a duplex reticle? Also, Burris Fullfield II scopes may be"discontinued," but they're (including 3-9x40 model) still available on Amazon, so stock up before they're gone. Those are the scopes you are looking for at two different price points.
