I'm in the market for bear protection. Planning a lot of hiking/kayaking next summer. I have shot the 454 with good accuracy for a first timer (borrowed a friend's). I'm curious what people who own either gun thinks about its accuracy, kick, and quality of specific brands. We could even throw the .500 into the discussion because i've been drooling over it too. I'm sure this has been the topic of discussion before but i'm interested in experienced opinions. I've been hanging out at gun shops (and pawnshops checking out used ones) getting a lot of different opinions.
