I carry the .40, 15+1.
It's very comfortable to shoot, and is very very accurate.
Many people say the trigger is gritty and get a trigger job, but for the life of me, I don't understand why.
Mine was smooth as silk out of the box, never has had a FTE, or FTF, and I love it.
One a side note: I think that getting trigger jobs is the new EP33N when it comes to gun owners and mall ninjas. They buy a gun just to get a trigger job to brag about getting a trigger job.
If you look at the M&P, don't believe anyone who says the trigger is gritty and needs the magical APEX trigger job, its Uber at stock.
