If ever there was a weapon that would be classified as only a weapon of terror with no practical application beyond fear.
Well, fear and burning people to death so they're no longer a threat. Not very efficient, but effective.
And I guess the "practical applications" of your guns, if they don't involve fear, involve gunning people down, right? Don't bother with scaring them off, just kill them.
Between you and me, it seems like the practical application of creating fear is working just great on you, quick-draw.
