I'm unfamiliar with this particular modification, but, there are any number of smiths who really specialize in one or another sort of work, and whose expertise is probably worth paying for, including the exorbitant cost of shipping. You want ports on your S&W revolver ---Mag-na-port, slicked & tricked Hi-Powers --- Novak, corrosion resistant plating --- Robar, superb Ruger MKx .22 pistols --- Clark Custom, high-performance tactical shotguns --- Vang Comp Systems, and etc. There's lots of generic work and repair work that can be done by jack-of-all trade smiths, but some specialty work is the realm of the masterful few, and it's usually worth the expense. (You're not gonna carry this piece in a generic nylon holster, are you?)
