I shot a Kahr CW9 (not CM) and honestly I wasn't blown away. The magazine seemed to be pretty chintzy in quality and the build quality of the gun was not especially great. That said, it did fire without error.
Maybe I just got a well-worn range model, but I'd be interested in comparing the C line to the P line.
The G26/27 I have plenty of time with, and it's a very high quality pistol, just a bit bulky.
As for the PF9, I'm not especially comfortable with Kel-Tec. Maybe the Ruger LC9, but even it has had troubling extractor issues.
Of what you listed I like the G26 best.
16 Pistols, 5 Rifles, 1 Shotgun, no time to shoot them
