Check out the ameriglo hackathorn sights. Amazon.com : AmeriGlo Hackathorn Sight For Glock 43 and 43 Front/Rear Green Tritium Orange Outline Front Black Serrated Rear GL- : Sports & Outdoors
I just picked up a set of these myself but am still waiting to try them out.
I actually just found those, well I haven't found them in stock any where, but I did find them!
They look close to what I like. I wish the rear sight had serrations on the back and that the front side of the rear sight was flat and squared off for one handed operations. But it looks as though it is the closest to what I want, unless I piece together some thing.
