The FBI continues to advocate penetration as perhaps the most important element of their carry ammo. To my knowledge, now that they have returned to the 9mm as a duty cartridge, they are going with the 147 grain subsonic.

While it is always fashionable to second guess the FBI, my response to FBI critics is: "upon what facts do you base your conclusion?" While the "sophisticated" among us own chronographs, the FBI has every imaginable ballistic measuring tool at their disposal.
