When I think of fire arms a pistol is always the most threatening even when it is holstered. A rifle is ok but a shot gun to me is the least and most intimidating. I like the shot gun because it is big so the police can tell very well if you are aiming it or just carrying it. A shot gun in one hand or over the shoulder says “I am not threatened by you and intern you should not feel treated buy me.” A shot gun pointed at you says... well you get the point.
I also now have my tent as part on my BOB.
