Copper customs work nothing but premium. If you want your Cerakote vision to be done right, I can't recommend them enough. I can also guarantee that they actually know what they are doing when it comes to proper application because my finish is very durable. I have had too many friends get let down by brand new cerakoted guns that started seeing significant wear only weeks after average use. My gun already has 600 rounds through it and a dozens of reps through the holster and it looks as good as the day I picked it up. I couldn't be happier!
