I've taken deer with a .44 mag (629) and 10mm (Glock 20). Recently I've been carrying a 1911 10mm while elk hunting. Colorado requires 550ft-lbs. at 50 yards and I'm just past that with a 200grain XTP bullet. I'd love to take an elk with it, which is not easy as I'd have to be inside 40 yards or so to feel comfortable making that shot. Someday...
