Front sights, rear sights & handgun stocks are a personal thing for all of us. When I was a younger buck & shot on the base pistol team I used black sights on all 3 guns, we blackened them often.
Now that I'm in my mid 60's those black sights are not ideal for ME, I have to have some contrast so my front sights get painted & while it might not be ideal, its much better than black for ME. For 40 years I've narrowed the front sight to .100" (they come .125" factory) this is a big help. Black sights in good light still work if I'm standing at the range in mid day....but I'm mostly a handgun hunter & many times the light is less than ideal, thats when the black sights fade really bad for ME.
I also like a peep sight & we make them for Rugers but they are not the best sight for long range work but out to 100 yds they work great. A gold bead is totally wrong for hunting because they fade into the hide on deer & elk, in good light they are ok. I tried one once in a USPSA match, wrong thing to do, they faded awful!
