M&P is my favorite poly.
I have the .40, never a single failure of any kind.
I JUST got the 9mm. Takedown lever won't stay down w/o constant pressure. AND it's keyholing…3-4 out of 10-12 shots…...i'll be sending it back to S&W today with a told return time of 3-6 weeks. Still no failure to fire/eject/etc. though which is great.
