#1 my eyes are pretty good. At late evening and nite, they go funky. I have a stigmatism.Euclidean said:Well, how good are your eyes?
Can you acquire a fast sight picture with the smaller sights?
Are you worried about certain size or profile sights getting snagged on the draw?
What kind of personal lighting options are you using?
What are you going to do with the gun? How often do you plan to carry it?
It's just one of those things that's very personal and particular.
I personally don't invest in anything for a gun for at least a month or 300 rounds, unless it's real obvious it needs it, like a replacement part.
