I know this is an old thread, but I just have to do a follow-up. After much consideration (and shopping around), I bought myself a brand new M&P 9, full-size, no thumb safety, internal lock, etc. I've actually had it for quite some time, but to satisfy the wife I agreed to keep it in the box until Christmas. Well, Santa brought some nice accessories, ProMag magazines, and several hundred rounds of Winchester white box practice ammo, and nice Cree light. All I can say is WOW! This is one fine pistol. I'm glad I made the jump from wheel-guns to a "plastic gun." Even with my fading eyesight, I'm getting some nice groups at 25 yards (even better at 15!!!). With a little more practice, I may even get something like what I'm accustomed with my K-38, and 66-2.
