I was hoping i could get help with a few questions i have about a used model 19 S&W in nickel. The gun seems in very good shape but i know very little about nickel finish. How does it hold up with regular shooting compared to blued guns? Any special cleaning needed? Also how much does it cost to re-nickel a gun and can a nickeled gun be blued? Lastly i was wondering what a good price would be for a gun such as this? It is in good to very good shape and i think it may of been a 19-3 but i could be mistaken. Thank you.
