I completely understand the single cop with a pistol, when he recognized a semi-auto rifle with dozens of rounds fired, knowing he was outmatched.

You are correct in a typical outdoor battle situation where combatants are separated by hundreds of feet and have body armor. But in close quarters against a most likely untrained shooter a trained pistol operator, with body armor, should not be "outmatched".

If I wielded the AR or AK, he’d not survive his entry.
