I was in the market for a new full sized pistol in either 9mm or .40 cal (.40 preferrred) and was not even considering the M&P because I wanted an external hammer and the option of single action. However, I have run into what looks to me like a fantastic deal on one with less than a box of .40 cal down the pipe. I can't find the model number on the Smith site though. On the box it says it's a 309300. I can find the 209300 which sounds identical to the one I'm looking at but the model number is different. Anybody here that can identify the 309300 and maybe tell me the difference. The gun comes with everything same as new plus about a half a box of ammo. The missing rounds are all the gun has fired. It has 3 magazines but the info I've turned up says they came with 2 magazines. Could that be the difference in the numbering? By the way, I can pick it up for $350 cash.
