Sorry if this is somewhat of a rehash, but the more I read, the more options I discover, and the less sure I am about what to get. I want a compact, very light weight, very corrosion resistant pistol to take backpacking, fishing, canoeing, rafting, etc. I'm considering a compact semi-auto (Kel-tec, Taurus, Kahr, etc.) in 9mm, .40S&W, 357Sig, or .45ACP.
I feel fine with ANY of these cartridges for defense against humans. The question is, which would be "least inadequate" for black bear or mountain lion? For this, I think penetration will count for more than expansion or caliber.
I realize that the 9mm is probably outclassed by the others (although it probably penetrates pretty well with FMJ ammo). But I'm much less sure how the others would compare if penetration is the major criteria.
Of course, I admit that I'm also considering moving up to a 10MM (Glock 29), or maybe one of the Taurus Titanium Tracker revolvers in .357 or .41 mag. But I'm reluctant to increase the size and weight that much (let's face it, the chances of really needing to shoot a bear are pretty remote, and I don't travel in Grizzly country). Your comments comparing the 9mm, .40S&W, 357Sig, and .45ACP for THIS PURPOSE will be appreciated. Thanks.
