well most of my conceal carry guns would be Illegal to use to hunt with, so, NO, I have never used one to hunt with
as a fact I don't I ever even came close to needing to ever use one , to hunt or defend myself with against a critter!
I did once however while dragging 2 deer out at once, have a very BRAVE coyote that would dash in at times and try and grab a leg on a deer
it was dark at the time and well, my hands were full, holding a rope in each, rifle over shoulder and pistol in holster
Coyote never really bothered me, and was just looking for a meal on a deer, so never felt in fear, or need to kill it,
every time I would turn to look at it, it would run off
went on for about a 1/4 mile then it gave up!

I personally carry a pistol, more for worries about running into humans with bad intentions or tend to get aggressive when I catch them trespassing! and am throwing them off private lands they don;t have permission to be on!
also don;t think my ammo on my carry guns would be very good on game, as its not designed for that!
all the more so on a big animal like a bear
IF I was carrying in Big bear country I would carry different pistol and ammo
