I only suggested it because it might be easier for a person to stun the person and make an escape for safety rather than pulling a trigger of a firearm and taking a person's life. I can't see whipping a gun out and shooting a person for the first time, life or death situation, is an easy thing to do. I mean hell every girl I know doesn't want to go hunting to kill animals and cries if they hit one with their car. It might be easier emotionally for the person to have one of those stun guns, incapacitate the robber, and run until the cops show. If you take out a firearm and hesitate even the slightest, whose to say the robber isn't armed and will likely retaliate.

As for the debate in the caliber, a .22 would not be a bad choice. A .22 round is strong enough to penetrate the human skull. Or even a 9mm. If might not have enough oomf, but again, a well placed round will kill a person. If you shot a robber in the lungs, heart, or the head he isn't going to be getting away.
