I will throw in my 2 cents for the Walther P99c. It is rugged, reliable, well crafted, and accurate. Also lightweight, hammerless, and concealable.
It has many inovative features and is a true single/double action striker fired handgun with second strike capability. Also the interchangable backstrap will adjust the size of the grip to the size of any shooters hand or glove.
That said, ...If you feel strongly about the Kahr, which is an excellent firearm; you will not risk "buyer's remorse" by acquiring it.
