^^^This.  It's an iconic and historic design; you can have a functional copy of the gun that fought in WWII, Korea, Vietnam, and elsewhere, and it's a reliable semi-automatic pistol to boot.  It's full of history and tradition without being so outdated as to be a liability in a shootout like a Colt Peacemaker would be, for example.  Added to the reliability is the option of getting an all-stainless model with exotic grip panels, and you've got a hell of a nice full-dress, open-carry-to-a-fancy-restaurant, self-defense gun.  That's a lot for any one other pistol to beat: It's near the top of the list for all of the following- reliability, history, looks, and function.
