I have a basically new (under 40 rounds fired) kkm 4.6 barrel. It fits the factory Glock slide. I also have heavy pure tungsten guide rod with the uncaptured 20 lb spring from the Glock store. I want $125 for the barrel and $100 for the spring. Will also throw in a gunfighters inc Kenia chest holster for free if interested. The holster is made for a streamlight tlr-1hl
