Well, I'll be the first dissenter and state that some of my favorite holsters are made of Kydex and not leather! My favorite open top holster is the Mad Dog Taylor Thunderbolt. It rides with the trigger guard at belt level (that's fairly low compared to many other rigs), which allows a short guy like me to effect a smooth draw. The Mad Dog Thumb Break for the Glock 23 has been a winner for similar reasons as the T-Bolt. Plastic gun and plastic holster are natural! The Milt Sparks Executive Companion was a great inside pants, when I carried that way. The Alessi ankle holster for the J frame Smith or a Glock 26/27 is the best ankle holster, period. I have yet to find a favorite thumb break holster for the 1911, though Lou and Dane are working on something for me.
