What is the threaded device in the picture above?
Also, there's something that doesn't look right about the cartridges. I also just noticed something else that seems wrong with the gun, unless it's just a trick of the light. Can you spot it?
I've never handled a Python, so I don't really know anything about them. But the more I look at this picture, the more I think this is only a replica. So what's the deal?
