The Kahr MK40 is the .40 S&W variant of the all-stainless MK-series micro-carry pistol, fitting 5+1 rounds of .40 S&W in the same 3-inch barreled all-steel frame as the MK9. It was introduced a year after the MK9 and represented one of the only all-steel pocket-sized .40 S&W pistols available at the time. The steel frame helps manage the sharper recoil of .40 S&W in a micro platform.
