God I wished I lived in a state where this wasn’t illegal.
I would put a single point sling on one of these and let it hang at my side or maybe even build a hip rig for it. This would be perfect for tight room clearing in abondoned/zombie infected buildings once they start walking about. And while the capacity is low, a handgun round doesn’t have the power a slug does. You can use this to open doors or take down multiple infected charging you in the hallway.
