Hello all. I'm new to this forum. I just noticed a small chip/removal of the nickle on the muzzle of my 4" Nickle Python revolver. I am not the original purchaser of this gun; it was not there when I bought the gun. I read some of the threads relating to nickle finish guns. Since my shooting is not affected in any way, I have not pursued, until now, seeking a way to get subject repaired. Any suggestions & can you indicate cost to repair it?
