there are LOTS of very good gunsmiths and gun shops out there, depending on YOUR area, as well as the factory itself for any refinishing....custom or different from original finish, then you must shop around, same goes for any and all "action" work...price is always the key word and custom or such and any and all additional "handwork" for 'prep' ( getting the gun to the refinish stage will vary these "prices"...a simple glass ( sand) blast and dip in the bluing tanks or in say black oxide, OR a parkerized finish, zinc or manganese, and it goes on and on,,,,almsot endless, again,one must shop around, check the shops in your area, get some price quotes...............standard for a "basic" normal "reblue" in this area is around the $125 mark...shipping of course, back AND forth ( to and from) will add to this as well as HOW or how bad your "pitting" ( rust) may be and the need for additional handwork adds to the 'price'.......call customer service at Ruger and ask them what they may charge, BUT remember over the phoine or the internet one cannot give a "proper" price quote as they NEED to SEE the gun, what it may need, then give you the 'total' cost.......so do not let this dissuade you..................much like an auto body shop, they are "estimates".............
