Free 40 cal ammo: WTT/WTB M&P 9mm barrel.

I'm looking to convert one of my M&P 40 cal compacts to 9mm. I have a 40 cal barrel with approximately 700 rounds through it. To sweeten the pot I have 40 cal FMJ/HP and 40 cal magazines. If your looking to convert your M&PC to 40 cal or have an extra 9mm barrel lets make a deal. PM for details.
