First of all, using what carry method/holster type? Second, what size is the Springfield 1911 - 4", 5", what? and gov't or officer's grip length?

Oh, also, what action type appeals to you? Do you, or do you not regularly train with an SAO pistol by drawing from concealment and making taking off-manual-safe second nature?
