As noted above, P series pistols are manufactured with
stainless steel slides that ride on steel inserts within the polymer frames, preventing the wear which would otherwise be inherent with metal slide to plastic frame contact. Available ammunition chamberings include
.380 ACP (P380),
9×19mm (P9),
.40 S&W (P40), and
.45 ACP (P45). P series pistols are noted for being very no-nonsense and utilitarian in appearance, with black plastic grips and a brushed stainless or blackened
Tungsten TLC stainless slides. 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. TLC coatings also serve to protect the slide from oxidization, nicks and scrapes. P pistols are known for having very smooth and consistent DAO trigger pulls of approximately six pounds, and large and easy to see sights in various configurations, including night sights. 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 P series is also noted for having a fully enclosed trigger transfer bar. 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. The PM barrel configuration boasts
polygonal rifling, which in theory will last longer and gather less fouling. Overall, an important innate advantage of the Kahr pistol design is that it is identical in function and trigger action across virtually all Kahr models, meaning that once a user becomes familiar with the handling characteristics and feel of one model, the learning curve for mastery of other Kahr firearms is much shorter. ==Variants==
