I have finally grown weary enough of my Gen 3 Glock 27 factory sights. I am looking to upgrade, but want to make sure I get the right set. I want something that has some generous light bars on either side of the front sight. Most sight sets are listed as G17/19/26, but I'm concerned that the shorter slide length will make the front sight fill the notch. Something big and bright would be nice. This is definitely a gun that is used in a daily carry role, with an emphasis on shorter range engagements. What are the state of the art right now?
