Apples and Oranges.
Kahr is essentially a world unto itself. I don't think there is another firearm out there with the same fire mechanism, or overall design. With a Kahr you get a very slim semi-automatic that has the double action trigger of a revolver. It is a niche product that really only competes with itself, at least for those people that understand its design and accept it for what it is. And what it offers.
I don't disagree that they should look into offering higher capacity models. Though how to do that without sacrificing the slimness of design presents the same challenge to them as it does to other manufacturers. But even if Kahr stayed exactly as they are their guns can continue to be sold and used as BUGs if nothing else. Very safe BUGs. As an example a P380 can be carried virtually anywhere. And makes an extremely capable last defense choice.
