What Material for Metal Pistol? Stainless, Polycoat, Nickel, Blued, etc.
I'm new to the semi-auto handgun world. It looks like the metal guns come in a variety of flavors; stainless steel, nickel, aluminum, polycoat, parkerized, blued, polished, matt finish, etc.. I don't understand all the different coatings, and the different finishes. Are there advantages or disadvantages to the different metals or finishes? What lasts the longest? Are some easier to maintain than others, or is this just an esthetic choice and they all are pretty equal? Is there a particular material or finish to avoid?
