OP,
Do you have any handgun hunting experience?
hundreds of head of small game, 2 deer, both with 9mm from a baited tree stand.
Anyone who can take deer with a bow can do so with a 9mm. It's just a question of setting up the stand properly, having a blind, where you can see them run 100m or more. With a good load and a good hit, from 20m or less, they never make it that far.
