M9 are pretty good pistols. The 9mm may not be all that but the pistol is not mediocre. I was in when they made the switch from M1911A1 to M9, guess which pistol less people BOLO’d with?
Did not say bad, just mediocre its a solid member of the “wonder 9” class but really its not a lot better than a High-power (13 rd vs 15)
No sidearm is stupendous with FMJ but 11.25mm is better than 9mm if one is forced to use FMJ
