Stainless is prone to certain problems. It is softer than carbon steel, so therefore not as durable in hard use. Also, stainless on stainless creates a gauling potential, requiring more care with lubrication. I prefer carbon steel guns, particularly pistols where friction is significant. My favorite finish is Armortuff, which is much harder than some of the others. I haven't had some of the others so I don't know about them, but Armortuff is better than the blued, black oxide, baercoat, or gencoat finishes I've had.
