A friend of mine who deals in bulk police trade-ins and such recently acquired a lot of 25 S&W 6906's. I picked up a couple for a little more than a song (lucky these days especially) and I have fallen in love with them. Carried alot but shot a little, I detailed stripped them to clean and replace springs, something I do with all my used gun purchases. I would like to obtain advice about refinishing or coating them with Duracoat or whatever. Stainless is not my favorite in autos but I love it in wheelies. What or my options as far as getting these two new additions pleasing to the eye? Will I run into trouble with a combination stainless slide and alloy frame? These will be working (truck) guns and flat black or gray is fine with me. If you have not guessed by now, this aspect of firearms is alien to me. Any advice will be greatly appreciated. Many thanks in advance.
