First of all congrat's on your purchase of the new S&W. I
highly recommend the use of Simichrome, a non abrasive
tubular (pink) polish that is available at most automotive
shops such as Auto Zone, NAPA, and other's. It cleans all
the residue from the front of the chamber's, top strap, and
forcing cone without very much effort. All you really need
is the polish and a clean rag, as the rest is up too you.
A small tube should cost approximately $5.00, and last
year's; almost a lifetime. I've been using it on nickel and
stainless guns for approximately 25 years, and I highly
recommend it. Good luck and safe shooting-
