One key (IMO) for anyone carrin' a 1911-pattern pistol is to make sure that the holster has a sweat guard/shield that separates the thumb safety from your body. I've had a few holsters that did not, and when I took the holster off I found that the safety had been disengaged by my inner garments sometime during the day.
Right now, I'm on a Minotaur kick and have 'em in OWB and IWB styles. They're comfortable, easy to draw/reholster, have good retention, have a sweat guard that shields the thumb safety on my 1911s, and Comp-Tac has them delivered to my door in less than two weeks after I order them.
