Before you do anything, can you describe this misfire? Are you saying the pin did not actually strike the shell when you pulled the trigger OR did it strike and leave an indent in the shell but the shell did NOT go off?
Most capable gunsmiths will be able to deal with Kemens but you need to know exactly what the issue is first, browning and miroku's suffer with an issue that only affects the bottom barrel and certain shells due to the pin hitting the primer at an angle which, when the pinwears a bit, means it does not contact the primer fully enough and you get a click and no bang!
