Since there is no separate Gun or Bow Bear season in WI, if your want you could carry a handgun or even a rifle or all three, it is legal. Just make sure if you use it, it qualifies as a legal big game weapon.
But if you are that concerned about a black bear in WI I would suggest you stay home. Bear in WI are not considered a danger.
I hunted in Douglas Co for over 25 years, Unit A1 for bears, most likely the most populas area of the state for bears. I'd see several bears every bow season while in my stand, walking to and from my stand and while having coffee on my cabin porch. I never gave them a second thought or considered myself in any danger.
Work hard and be true to yourself.
