I carry my Taurus Millennium Pro .45 ACP every where its light easily concealed and 11 rounds. If bear are a concern load FMJ and aim for the head.
Chose something you are willing to carry all the time and know how to use it! S&W does make a nice light weight .44 mag but if its back at camp when you
need it you're SOL! The key is what are you willing to carry all the time?
The price of freedom is eternal vigilance.
