Can someone....

Re-finish a barrel for me? I want to purchase a ported barrel for my G19 (since threaded barrels are illegal) and most come in a silver finish. My G19 is OD so for aesthetic reasons I would like the barrel to be black. Anyone know anyone?

Buy a bottle of Cold Black from Brownells. You can do it yourself and have the rest of the bottle to redo once a year or as needed.

If the "silver finish" is stainless steel, bluing won't work.
You will need black oxide to make it black.

If it's chromoly steel, I can parkerize it.
