I'd remove "Demand" from the equation. Request nicely works a whole lot better anywhere you go.
The slide is wrong and I'm certain they will address that. The angle of the feed ramp is probably ok, I am concerned about the marks at the bottom. I don't have a 380 so I don't know how much that bottom of the ramp effects things.
I wouldn't do anything including shooting it until you get a response from Kahr. Another email suggesting "in a nice way" a replacement and concern about the barrel feed ramp is the next step.
