Look at the POF Tombstone. Lever action magazine fed 9mm. Spend but they make them.The 9mm lever (tube fed, or possibly rotary mag) is something I've wanted, BAD, since getting my suppressor. AR is fun but action is still loud... 38 lever gun is QUIET, but would be great to use 9mm.
500 s$w lever gun that's affordable is a real good idea too...
