The Kahr action is a Browning locked-breech design featuring a striker-operated firing pin with a passive firing pin safety, making it a true hammerless action. When the trigger is pulled, the trigger bar begins to rotate a double-lobed cocking cam. This cam simultaneously begins to draw the striker to the rear, compressing the spring behind it, while depressing and deactivating the firing pin block. At the end of the trigger's travel, the lobe contacting the striker slips off the striker and releases it; the other lobe has, by this point, completely depressed the firing pin block and permitted the striker to snap forward and strike the primer. This single piece takes the place of more complicated and fragile designs employed in other pistols. It is similar in principle, though very different in execution, to the action design of Glocks. It also allows the firing pin block to be located further to the rear of the slide and therefore further from possible contamination by combustion gases and powder fouling. For this innovation, Justin Moon was awarded one of the five patents he owns on the Kahr pistol design. This system is employed on all Kahr pistols, regardless of frame material, size, or caliber.
