Just installed my sights, what a difference a day makes.
I don't care what some say about white dots, when the light is low or you are a seasoned citizen there all dark to me, but now "let there be Light".
You see I can't focus my eyes close enough to see the white dots clear without my glasses and in the low light I had black nubs.
But now my friends, now I see the light, green light. Since I am instinctive shooting anyway, these sight clear the way.
You can get you center alignment from the hip, being that you are not target shooting but defending yourself, center mast is what you want.
Buy them if you are like minded, don't if you still have 20 year old eye's
