Hunting with a semi-auto pistol isn't very common, and theres a reason for it. Most have
nonmovable (and for the most part highly inaccurate in the ones i've shot) factory sights that dont let you aim much above 20 yards.

Havent you ever seen Dirty Harry??

Honestly, if you're worried about it that much, get a 6" 41 mag revolver thats lightweight (Taurus makes a good one from what I hear) this should do double duty for you, though I'm thinking you're still several years away from CCW??
