My .357 sig is spost to be more powerfull than a 45 auto, but I never hear of someone hunting with them.Id like to shoot a hog with it.Im useing 124 gr.hp-xtp bullets,blue dot at 1350 fps.that shud do the job.
Not me, but I imagine it would be fine for close up medium sized deer using the heaviest bullets they make for it. It's not comparable to the .357 Magnum, though, because big game hunting bullet weight for those start at 158 grain and move up from there. The Sig won't handle the heavier bullet weights.
PS Besides, it would "way over penetrate."
