Don't get me wrong, I like the Dawson sights as well. I just prefer a deeper rear notch. I don't have any Bowmars to compare to.
In terms of the light at the rear, I ment under the back where they hang over, not under the notch.
I not sure the cost of burying sights is worth it either. All things considered, if adjustable sights is a must, I would still go with the Dawson, and deepen the rear notch.
For fixed sights, I really like the Heine sights, with the front thinned to a hair over .100 or until you can start to see the sides of the screw hole.
