Well, you will find that the S9 is significantly larger than the Kahr PM9.
Second, although the M & S are only 1/2" different in barrel & butt, it seems to make a pretty large difference for carry.
I have my permit, but don't carry on a regular basis. However I do have an IWB CTAC from CompTac, and I notice that the S9 prints far less under a shirt than the M9; that 1/2" in the grip length seems significant.
As far as capacity goes - I just performed a magazine mod that gets me 12 + 1 in the S9. Basically, the S40 magazine can be modded to carry 12 rounds of 9mm instead of 10 rounds of .40. But since S40 magazines seem to be impossible to find, I had to "make" my own. Details on that can be found in threads on this site, and further explanation can be given if you are interested.
Either Steyr is a good choice, IMHO. I've had my M9 for a while, and only recently picked up the S9. I like the balance of the smaller S; though I still love the M9, of course.
Personally, I think I will eventually pick up a compact 1911 or other slim pistol for CCW. I wish someone besides Kimber made a 4" barrel 1911 with a stubby grip; most makers seem to go "compact" all the way, with the shorter grip also coming with a 3.5" or shorter barrel/slide, which I'm too afraid to take a chance on; I've heard lots of reliability problems with 1911's under 4" barrel length.
