[7] Early Kahr models such as the K9 were praised as well-made and solidly constructed, but criticized for their excessive weight, which is a disadvantage in a weapon intended for concealed carry.

[8] Kahr attempted to address these concerns by introducing a line of polymer framed models.

Produced by applying a thin but tough protective coating, the TLC patina was labeled "Black Diamond" in early production, and is valued for its lack of attention-catching light reflection in dim surroundings.

Simplified controls exemplified by the lack of a manual safety lever are also positive attributes and contribute to a desirable package for concealment use.

The engineering design work necessary to fit it inside the cramped space of the receiver resulted in several beneficial lockwork changes.

One such change was that the cartridge feed ramp had to be offset, which in turn allowed the overall receiver design to be thinner; it also permitted the slide to be more squat with a low bore axis, resulting is less muzzle rise and flip.

[7] The PM barrel configuration boasts polygonal rifling, which in theory will last longer and gather less fouling.
