I agree with the 2 previous postists--if you want to protect yourself in the wilds from bears, use a 10mm. It will NOT be pleasant to practice with, but practice you must. The small size of the 29 will make it even tougher to control, but a mag extender will help.
Even a .40S&W will be better than a .45GAP--and I love the latter for home defense, in a full-size model 37--but the .45GAP does not handle the heavy bullets you'll want to use for protection against dangerous animals.
Personally, I think you'll be better off with a Compact-size .40S&W model 23--13 potent rounds in the mag. and easier to shoot than a subcompact.
