S&W does a lot of things that don't make total sense to me.I don't think there's a single difference in their .40SW and .357Sig except the barrel. Beyond that it's just markings and packaging? Glock clearly sold enough of theirs. I just don't buy it, unless they are just completely eat up with the Kaizen/Six Sigma/Lean BS in their accounting dept. which is entirely possible, I've seen some really stupid stuff in that vein.
