Just remember Svaldard requires a long gun for Polar bear protection. Wise legal requirement.
I would probably also carry a 44 Magnum. Or a 10 mm with Double Tap, Buffalo Boar or Underwood Extreme Penetrators, minimum.
But both guns can be hard for a woman to shoot. You'd need to practice with them beforehand.
All bears are extremely aggressive and will come at you very fast and relentlessly. Especially Kodiak and Polar bears..π«
