Larry Vickers has a set of sights for the Glock coming through a collaboration with Wilson Combat. This is a prototype but the final production ones will be very similar; the hole at the bottom is for a tritium dot allowing for a dot-on-top-of-dot tritium sight picture. The rear sight is a “U”-shaped affair with scalloped sides. So far, LAV has made no mention of the front sight.
