If you think you have an advantage and can win, engage. If not, wait until you do have an advantage
No longer than this particular scenerio lasted, I don't believe there is time to gain the advantage. These guys were pro's, I'm no new age, Hawkeye optician-minuteman, but in my opinion by the time you assess the situation return to your vehicle to grab a useful firearm....you know, something other than a P3AT, it's over.....people have died, bad guys are gone.
