Hello friends, I have an XD-40 Subcompact, and I'm shopping around for some night sights. I'm considering Tru-glo TFO's. My question is: Is there a signifigant advantage in having the front sight a different color? Or is the ones with all the same color sufficient for me? The only application I'll use the night sights & pistol for are home defense & occasional CC. Thank you.
