Helps with contrast for sight acquisition - Trijicon H&K P2000 HD Night Sights

I have not tried them at night yet but the color does help with visibility at the indoor range I go to and they seem to pick up any ambient light and magnify it to give a good contrast. The stock sights on my H&K tended to wash out some with the lighting there with my eyes not being what they use to.These helped allot and sight acquisition is quicker also as the sight pops into view to my eyes easier. Being that this is my carry gun it better to have them.The sights sit up a little high and this tends to make you make an adjustment to your sight picture. With the sight a little higher it tends to have a small effect on my holsters.
