My experience has shown that reliability suffers with increased concealability. I have come to be a very firm believer in carrying as big as you can. Obvious, not all situations allow for a 1911 or CZ75 on everyone. Kahrs can be picky, that's for sure. For mine (CW40), the "200-round break-in" couldn't have been more true. You have to treat your Kahrs like babies until they mature. Kahrs are NOT for beginners, in my opinion. They get away with it, and many put up with it, because of the lack of competition in their size class. Time will tell if other companies can make more reliable products that are the Kahr's equal as far as concealability. The XDS looks promising.
