I have had a M&P9, and yesterday I bought a NIB M9. My reasons: I wanted a 9mm pistol for the range, and not for carry...I have other handguns for that role. I have a 9mm 1911, but I wanted a DA/SA pistol in 9mm too. I preferred metal, not polymer, and I wanted a safety/decocker. I wanted a pistol for which magazines and parts are usually available from aftermarket suppliers, and not just from the manufacturer. I wanted a pistol that is reliable and easy to maintain. That came down to a SIG or a M9/92FS for me.

I have had a SIG, in fact a couple of them, but I wanted something different. I like the feel of the M9, plus it's role in our military history was a positive for me...so that's what I got.

The M&P9 is a great pistol...but as I said, I didn't want polymer, so that put it out of the running for me. If you want the M&P9, it will be a great choice, and S&W has fantastic customer service if you ever do have a problem.
