I thought they were bringing back the 4506 in honor of Vic Mackey, the lead character on "The Shield". If they are going to make a single stack M&P, I am sure it will be a huge hit, and it will trounce Glock. People have always wanted a single stack Glock. Those baby Glocks are too fat. I don't like striker fired guns, but if they make that with a manual safety or a mag disconnect (even better if they had both features for me), I will own one.
