I would advise caution in approaching a "local plating shop".
Many of the processes they use can harm fine finished items especially if they are made from more than one metal. The old style electrolytic process for stripping Ni from steel will destroy brass, bronze, and copper parts in a twinkling, and severely etch the steel if the operator does not take care. In my experience plating shops also specialise in losing small parts.
Brownells sell a universal nickel stripper that comes in a two part liquid formula that will safely remove nickel from virtually any substrate without etching it. Without seeing a data sheet or MSDA I can't say exactly what the formula is but I can hazard a guess, and it'd be safe enough for both the gun and you or your gunsmith. That's the way I'd go.
