Point and shoot... that's all there is to it. - XS Sight Systems DXT Standard Dot Sight - Glock

I have had these sights on a few different guns, most recently my Springfield XDs 4". I love these sights. Its point and shoot. That's all there is to it. Where ever the front dot is, is where the round will hit. No searching for a blind front sight through the rear "window". You just dot the "i" and fire away. I highly recommend these sights.
