I picked up a new S&W M&P .40 range kit from my dealer last week, seems like a nice all around kit for the money, I noticed something different from my previous M&P pistol, the new one is not marked stainless on the slide. I looked on the S&W website, noticed they list the frame a polymer, the rest of the non kit M&P's are listed as Zytel polymer, wondering now if the range kits are a cheaper version lol, any input?
