No- nothing wrong with the 45ACP- other than it has a weak case head and is way turned down for use in an auto. If I were going to carry a 45ACP in a revolver, I'd use 45Super brass and loads. My point is that if you want a 45 caliber carry piece, I'd either want something small like the little Smith revolver, or if I was going to carry something as large as a Taurus Judge, I'd just carry a 13-round capacity auto pistol.
