So if Kahr has a tough time controlling their customer service personnel, what does it say about their QC? If, as your post suggest, 10% pay for their own shipping, is 90% a good success rate for a $700+ gun?
To their credit, Kahr did make it right, but I do expect a "teensy weensy" bit more from a company charging that kind of money.
So do you work for Kahr?
