This is my first post and first M&P. I bought the M&P .45 full size and put an Inforce 200 lumens rail light on it. I took it out for the first time the other day and really like the way it shoots. Only problem so far is one of the mags doesn't want to hold 10 in it. The other one does with no problem. I got 10 in the one that I'm having problems with but can't get it in the gun with a full mag. I ordered 2 more mags yesterday so will see how they work. So far I really like this gun and the way it fits my hand with the MED back strap.
