I like the El Paso Saddlery Tanker holster, but if you've got a barrel longer than 5.5" I'd go with an "across the chest" type holster like the Barranti, Simply Rugged Chesty Puller, or the 7X holster Whitworth has. The Tanker holster, as can be seen in Mackay's pic, is more of a mid-stomach holster than a true chest (as in, over the sternum) holster and unless you're really tall, a barrel over 5.5" could be a bit unweidly in a Tanker style holster.
