Reminds me of the gun they gave Cas in "Two Minutes to Midnight," which looks a LOT like the gun John Wayne buys James Caan in El Dorado after requesting "a gun for a man who can't shoot" from a gunsmith. That had a doozy of a kick to it, too. Poor Cas!
Well, poor everybody, really. I'm enjoying this story, but it does hurt to see them all struggling so.
