The Newsmax.com reports:
Wisconsin’s gun laws are lenient when compared to its neighboring states.
To purchase, own, and carry firearms in Wisconsin, residents don’t need a permit or license for handguns, rifles, or shotguns, according to the NRA-ILA. There is, however, a 48-hour waiting period for a permit to purchase a handgun.
Wisconsin is also an open carry state, which means citizens may lawfully carry a firearm in public. They may not, however, openly carry a weapon in a vehicle.
