In my (somewhat limited)experience, $470 is a reasonable price. I bought my last XD40 at a gun show more than a year ago for $460. As for the 9mm vs. .40 argument, it will never be resolved. My wife and I both carry XD40SCs (legally--we have Texas CHLs). I have an XD40 Tactical in the bedside table. Our son (also a CHL holder) carries an XD40SC--but his wife swears by her XD9SC. You pays your nickel and you takes your choice.
