I'm sorry, but maybe I am a bit confused. You are having trouble making hits at 50 yards with a rifle, so you are going to hunt with a handgun which is harder to hit with, less powerful, more critical with regard to shot placement, and even more range limited?
Do the animals a favor. Practice with whatever gun you chose and don't take shots beyond a self imposed range limit that you feel like you are confident at. If there is a back-story I missed, I apologize.
I see you're not a handgun hunter..
