If it's got to be a 9mm, to me there are only two choices:
HK p7m8/psp if you like em thin.
g19 if you want lots of rounds.
Kahr does nothing better than the p7, and carries less firepower than the 19.
g26 is not really much more conceable than the 19, and is much less ergonomic.
Oh, the third choice (if full auto is allowed) is g18 with a couple 33rd stick mags carried under the shirt.
