If you own the .41, that's fine... Not that much different from the 44 for what you are using it for.

If not then I would go with any magnum handgun that you have a preference for and are comfortable with.

Think about it this way, most people carry pistols for protection. Very rarely do they think about raw functionallity and purpose. Having the most powerful handgun in the world won't do you a damn bit of good if it doesnt fit your hand, your proficiancy level and your tolerance to recoil. You want to be damn proficient in the instance of a bear charging you.
