prairiedog555, I have a Sig in .357 Sig. I would never consider it for hunting. Will it kill a deer at short range it hit in the right place, yes. Is it a gun that should be used for hunting, no, not in my opinion. Like pastorp said, there are better choices.
The bullet design for the 357 Sig are not bullets meant for hunting. The are fast expanding bullets meant for defense agent man.
Get your self a Revolver in 41 Mag or bidder for hunting or if you are set on a semi-auto get a 10 MM.
