The comparison of Kahr (and Glocks as well) to revolvers in terms safety leaves a lot to be desired.
While it is true that the Kahr (and Glocks) has a relatively long trigger pull like a revolver, you generally feel a good deal more resistance with a revolver trigger pull than the trigger pull found in a Kahr (particularly in the smaller Khar-sized revolvers). The other, and to me far more telling difference, is that there very obvious visual and tactile (and sometimes aural) indications something is happening with a revolver (e.g., the hammer is moving back and/or the cylinder is moving). With the Kahr, there is no such tactile/visual clues, just a loud bang at the end. A revolver should be holstered your thumb riding hammer (or finger contact with the cylinder given a "hammerless" revolver--a tactile and visual warning something is amiss which you do have with a Kahr (or a Glock).
FWIW, I carry a Kahr K9, but to compare it to a revolver is terms of safety while is a stretch.
