This is a story about four genuinely insane offshoots of what could be argued as one of the most significant inventions in the history of humanity: the gun. 

I'm not saying good, I'm not saying bad. I'm saying significant. 

That being said, this episode is about the world's largest double-barreled cannon, the first rapid-fire artillery with one glaring error, a questionably disguised triple pistol, and of course, a gun exclusively made for telling the time.
