I've had my M&P .45 for about a year. After about a thousand rounds with no issues, I decided that the trigger, while ok, could use a little love. Mike LaRocca did the work and now I have about a 4 lb pull, no creep and very short reset; money well spent. The slide will sometimes release and chamber a round on its own when seating a fresh mag. I consider that a feature instead of a bug. I had the opportunity to torture test the .40 and the 9 minimum a couple of years ago. We put 5K rounds through both guns, shooting more for speed of rounds downrange rather than accuracy. Every 100 rds. shooters were changed and temperature readings were taken. We were unable to make either gun choke; although one young lady singed her finger on a hot slide. I bought the gun as soon as it came out in my preferred caliber. If I had to take a pistol to a gunfight, it would be the M&P. The only other mod was a 10-8 rear sight and a F/O front. Excellent weapon, highly recommended; I consider it ergonomically superior to the Glunk and the ability to swap backstraps as well as the mag release position are a big asset. My gun has the external safety but not the mag one. End of infomercial.
