HI,
I live in Washington State. I am looking for a gunsmith that can install A compensator on a Tangfolio Limited Custom 9mm. I have ordered a Eric Grauffel coned compensator. I haven't ordered the barrel yet. figured I would order a 6' 9mm barrel to be cut down and threaded. I just need to find a gunsmith with the tooling and experience to do so. Any help would be greatly appreciated
