A good friend is planning a canoe trip in the wilds of Alaska this summer. He is planning on taking along a rifle (45-70) in case of emergency, animal attack, etc.. Thinking about some documentaries I've seen on bear attacks, I'd personally feel more comfortable having a side arm that was on my body 100% of the time. I realize no side arm is an optimal bear defense weapon, but no doubt its better than hand to hand combat. So, as he only has some smaller caliber pistols, I offered to loan him anything I have that might be appropriate.
My question is, from the above list of choices (what I have that may seem to work), what would you feel the best one, if any?
S&W 659 6" .44 magnum
S&W x59 2.5" 44 magnum
Colt Delta Elite 10mm
S&W 1006 10mm
Glock 21 10mm
S&W 4506 .45acp
Glock 20 .45acp
and not very practical; Desert Eagle .44 mag
Other than the Glocks and DE, all are stainless steel with synthetic grips.
We're planning to meet up at the range so he can try out any of them that he's interested in and we can purchase any ammo that would be optimal for the purpose that I may not have.
I'd appreciate any input you all have. TIA!
