Hello I'm new here and was hoping someone could help me. I few months ago I saw a post somewhere about a new design of sight for the Glock. It only had a rear sight and was extended almost to the ejection port. The concept was invented by a Jewish Doctor or something and basically consisted of a tunnel with a lighted end at the front so that as long as you could see the sight, the gun was on target. Does this sound familiar to anyone? I have been scouring the net for info on in for quite some time. Thanks!
