I use a Kydex (IWB)
I have a Kahr MK40 that I carry all the time in a Blade-Tech (Ultimate Concealment Holster) and I love it. The little Kahr just disappears under only my tucked in shirt without the need to wear a jacket or loose shirt. I carry it at the 8:30 position set for the FBI Cant. Yep, I am a died in the wool "LEFTY"! It is so comfortable that I forget that it is there, well that is a white lie I never forget it I just don't notice it.
