The way to prevent accidental discharge is to keep the rifle slung over one's shoulder, with an empty chamber, rather than nervously gripping it with one's finger on the trigger guard as pictured in TFA. That posture serves no purpose other than the intimidation of the ignorant. And it's clear from this picture the magazines, if they exist, aren't secured in one place on a sensible leather belt, but rather are rolling around in the bottom of one or more of those giant pouches he's got hanging around.
