Oops, I should point out that nickel finish scratches easily and for some reason powder stains are difficult to remove. The finish is fine if you just buying the gun to stare at and parade pictures on the net. They look great with pearl grips. I used "duty version" (fixed rear sight) of what you seen.
I picked up worn nickel 4in about 10 years ago, pro-shot makes a lead clean cloth and metal care cloth that can make them look like new with some elbow grease.
