In my experience, there's a die-by-the-sword tendency for Gunluggers.
In a game I ran over the winter, our Gunlugger, Rue, progressed steadily for a while. I think it was when Rue got attacked on foot by a dozen bikers and won that he finally lost all caution about using violence.
A siege, one melee, and two shoot-outs later, Rue finally pissed off the tenant farmers badly enough that about fifty of them picked up rocks and pelted Rue until he collapsed. He had 2-armor, but a miss on a 0-harm roll is still bad, and when he hit the ground, someone took his gun away and shot him.
I think it's no accident that Rue's home was inside a drainage pipe (which was chosen by Rue himself) - social interactions are dangerous, but too many interactions that end in violence is pretty bad too, so it's better if the Gunlugger can get away from it all once in a while before s/he ends up burning down the town.
