“After people new to shooting, and carrying a gun for self-defense, settle on exactly what their carry gun will be, inevitably there comes the time they ask themselves what should be their next gun purchase… such people, when they ask me, ‘What gun should I buy next?’ are always amazed when I tell them, ‘If you’ve settled on Gun X as your carry gun, what you really need now is a second example of Gun X.’ I call this concept the Replacement Gun.”
