Great sights, but could be better.. - SIG SAUER X-Ray3 Pistol Sight Set, No. 8 Green Front, No. 8 Rear, square

I think these are great sights. I had the Sig night sights before and the only issue I have with them is that at night it is hard to differentiate rear from front glowing dot. I was hoping that this sight had a more differentiating front sight at night. However at night all three dots glow the same color. So the only improvement I wish for is a different color glow on the front sight at night! Day time performance is excellent so worth the upgrade in any case.
