I've heard about these but I actually saw one in a gunshop a week ago. I totally forgot the price but it wasn't hugely expensive... 500, 600 bucks? Any more I probably would have remembered for sure.

Pretty neat little pistol! It's .357 so it shoots a badass round. It's also probably a complete waste compared to other, more reliable revolvers with more capacity and accuracy. But you're the one who wants a modern pepperbox, lol.
