I am wondering what you all think about using an orange or yellow front sight and green or secondary back sights. On my Glock 21 I have all green night sights. I find it hard to pick up the sighs at night when shooting at the range. I have seen off colored front sights for sale and just want to know if it is worth the $'s. Have any of you used two different color of sights in the past and do you find you can pick up the front sight faster and keep on it better? Stay safe and keep shooting.
