Kahr CM40.

The CM4043 is chambered in a .40 S&W caliber, has a 3.1" barrel and an overall length of 5.47", with a height of 4.0". The pistol weighs in at 15.8 ounces plus 1.9 ounces for the stainless steel magazine. Differences between the CM models and PM models include: the CM4043 has a conventional rifled barrel instead of the match grade polygonal barrel on Kahr's PM series; the CM slide stop lever is MIM (metal-injection-molded) instead of machined; the CM series slide has fewer machining operations and uses simple engraved markings instead of roll marking; and finally, the CM series are shipped with one magazine instead of two magazines. The black polymer frame features patented 4140 steel inserts molded into the frame in the front and back for added rigidity and strength, which can withstand firing thousands of rounds. Kahr's cocking cam trigger system employs a patented cam to both unlock the firing pin block (passive safety), and complete cocking and releasing of the firing pin. Kahr's two patents covering the offset recoil lug and the trigger bar attachment allow Kahr's barrel to fit lower in the frame, and since there is no hammer, the shooter's hand is further up the grip resulting in less felt recoil and quick follow-up shots.
