The trick with .40 S&W is that as long as there continue to be cheap police trade-ins on the market, nobody is going to buy a new gun chambered in the round.

Seriously, the majority of people — including those who insist that they'd buy it at any cost — are going to change their mind really fast when they see that they can buy a couple SIG P226s, Beretta 96s, CZ-75s, or even an old S&W 3rd Gen for the price of a new M&P40 Metal Frame.
