RE: 9mm luger for deer hunting???
I have some important questions in response to your 9mm inquiry. Where are you hunting and what size are the deer there? Florida has these tiny little deer that I would think a heavy (158+), maybe +P, or +P+ would do a nifty job on at close ranges you described and you can drill the hole where you need to. Can you get + ammo in your area or is it LEO only? Are hot and heavy handloads an option?
Another consideration....................
most everyone's got a shotgun around. Any 12 or 20 smoothbore with foster slugs would more than adequate - no matter the size of the deer. Just go get some Sluggers or something and there will be no question whatsoever as to whether or not there's enough energy available to deliver to your target.
