Personally, I do not see how "most" globe front sights are good during hunting, especially in low light conditions.
My GPR is now wearing a Lyman 57 peep that I drilled out the aperture some. I still have the factory front bead but am looking to change that to something better. And here is the reason why. Last week I took it out squirrel hunting and could not, for the life of me, see the front bead to align it on a squirrel that was close up. And it was not due to the peep. I could see the squirrel just fine.
It is to my belief that unless someone has some sort of front bead that illuminates well (such as the one BS has posted) then any other front globe sight would be counter productive for many hunting applications, especially during lower light conditions, which is often the most critical time.
