And there is always pocket carry. I actually took this picture complaining about the holster in the middle, which I cut up, but I cut it a bit more and have been carrying it for a couple of days with the PM9 Kahr. I generally wear Dockers style slacks for work and nicer cargo style pants casual.
Larger guns can be a bit uncomfortable, but nobody ever notices. The PM9 is about the max size for pocket carry.
One thing nice about pocket carry is you can casually slip your hand into your pocket and have gun in hand (in pocket) if something seems "not quite right".
