Perhaps the wife has expressed an interest in self - defense tools. The man, being supportive, goes ahead and buys her a stun gun. It could also be part of a broader plan for home security.

He may think it's a good way to keep her safe. Simple as that.

Sure. Once, a security guard was demonstrating a stun gun to a group of new recruits. He accidentally zapped himself instead of the dummy. He jumped around like a crazy kangaroo for a few seconds, much to the amusement of the recruits.
A hiker was alone on a trail when a wild animal approached in an aggressive manner. He used his stun gun, which startled the animal and made it retreat. Stun guns can be useful not just against humans but also in certain wildlife encounters.
Sure. Once, my friend thought a stun gun was a flashlight. He was showing it off in the dark, accidentally pressed the trigger, and zapped himself. He jumped about a foot in the air. It was hilarious seeing his shocked expression.
You can sometimes find stun guns in police stations or during certain missions. But it's not that easy to come across them.
Maybe he thought it would make her feel safer when she's alone. Could be for self-defense purposes.
