Came across this snap-on loops OWB Kydex holster design from http://www.x-concealment.com, from user X-Concealment's post in the Classifieds section here. I now have a Generation 2 "C" Series Snap-on holster from them for my Glock 23; only 5 days from ordering! The top snap on each side is a 1-way "Pull The Dot" snap. The fit & finish and craftsmanship is outstanding, and the adjustable retention screw works really well in fine tuning my preference. I highly recommend them!
