My guess would be hunting and also the possible presence of a firearm in certain situations acting as a deterrent as well as a potential social equalizer.

When you're a physically vulnerable person and there are zero firearms in a community (and it's known there are zero), then there's no physical deterrent to attacking you. Of course in theory there are social consequences, but if you're in a society that includes things like alcohol or other substances, teenagers/people with poorly developed senses of long term consequences, or mental illnesses, then the thought 'oh shit, she/he might be strapped' might do more than 'you might go to jail'.
