Gun is a good thing, but way more important is organization. I mean organization like "when order came everyone stands up and fights no slackers".
Even 10 organized people with no weapons are _way_ more dangerous than one armed person. That's why all autocratic regimes firstly jail/kill organizers (right now it's Turkey). Just having eyes in 10 different places is more important.
As Jefferson really liked (proposed by Franklin): "Rebellion against tyrants is obedience to God."
