I highly agree with both of these gentleman! Ive also got xs big dots installed on my gun, and contrary to the rumors, these sights can be very very accurate when the correct sight picture is used! I also recommend heinie straight eights, and ameriglo Idot pro's. The heinies are a two dot system like the xs big dots are, but the rear sight is a notched U-shape like stock glock sights without the white outline. So at night you have the glowing dots where all you have to do is put one on top of the other and fire. And during the day you have a sight picture that is nearly identical to the stock glock sights, minus the white outline, which you really dont need in the daylight...
