my three weapons are
1. M4 scoped because it gives you range beyond 500m as well as a 28 round magazine while keeping the ability for close quarters combat
2.9mm pistol hopefully glock or sig mainly because you can carry 15 rounds in one magazine and one in the pipe or if you can find an older magazine or you don't live in a state were they are stupid you can have 19 rounds with your 18 round magazine
3.second 9mm pistol mainly because knifes aren't weapons to be used against the undead so i consider it a tool for survival and pistols will give you average range of about 50 meters beyond that i can use my rifle and you can carry tons of 9mm rounds
I think he meant using pistols in close quarters or last stand situation. Being pinned down with chomping jaws above me, left hand holding the head up by the neck, i know id rather reach for a revolver rather than a knife. But you always need a knife, for survival, hunting , it's a bare necessity.
It always depend on whick part of your body you put your gun, i have a pistol behing my back under my shirt, also i thought of a little revolver in my boot, so if i run out of ammo and i have zeds running close i can take them out , also like you said, if i fell i can get it from my leg.....or maybe a sword or knife....
