I can't imagine a wife encouraging her husband to buy a gun. If my wife started now I'd worry that something was wrong. I can understand a woman acting that way with an angel for a husband. I'm just happy to have one willing to live with me.
My wife was raised in a hunting/fishing oriented environment*. She's also an very active pistol shooter and belongs to two different womens shooting groups.
