The same reason why the US military hasn't dropped the M9 is the same for the M16/M4 platform. One is partly because of contracts to the companies that makes them and that a weapon is meant for a specific purpose isn't worth the money to replace en mass. Not everyone on the front line is issued a sidearm and their pistol training is only basic level.
A military as large as the US has bought so many of them that the cost of replacing it is incredibly costly for the defense department.
For civilians, we can get modern defensive 9mm ammo that are hollow point and can cause more damage to stop an unarmored target. In the military world, they aren't allowed that and the 9mm can only do so much if that's what you have left. The military is more worried about how effective is their current rifle platform, which isn't that bad.
It all comes down to cost.
