I'm late to this thread, but I think the gist is this. Mount the caliber to the job. Human SD, 9mm is fine (I'd still go Glock, SiG or M@P in that order before your choices), but go Berretta of the ones you listed. For bears and lions, 10mm is the only semi I'd look at and the G-20 is reliable and the same price as the Berretta ($500-$550 give or take). Personally I'd just go .44 mag or or .454 Casull which which will let you down load to .44 special or .45 Colt for SD or practice in a wheelgun.
