Glock charges $45.00 to refinish a slide. The current finish is different from the finish on a early gun. I was going to have the slide refinished on Frankenstein, my Glock 17, and the service techs advised against it. I was told the finish on my gun was far more durable than the current offering, that I should just use it as it is. CCR that advertises on the forum has a stainless looking plating finish that looks real nice.
