I know its new and tight, but sometimes I'm a bit concerned about how much force it takes to close it.

BTW, I'm assuming the fiber optic is photo-luminescent? It glows and night and I seriously doubt it's the tritium element in the optic. I suppose I could be wrong though.
Its the reflection off the Tritium that your seeing, if you look closely the fibers are picking up some of the light from the tritium making it look like there glowing a bit. Yes the rotating cover is tight, it will loosen up the more you play with it, you could put a drop of oil on the edges to help it rotate,
