No, but maybe they have fancy glow in the dark sights? I'm not trying to stir things up just curious I've never seen a surefire but I've wondered how good they would be with regular sights. I just checked out my 590A1 with a flashlight held below and beside. You are correct you can indeed see the contrast of the sights with the light below, but on the side the front sight glows orange and is even easier to see. Also depending on the surrounding lighting it's not always easy to see the sights from what I've tried. Tritium sights would help alot.
