Because the chances of me successfully holding off 6-7 armed men with my PT-111 is very slim, doesn’t mean I won’t try but I am a realist. If my family has time to put in effect our response plan then we hole up in the master bedroom, with an M1 carbine with 60 rounds, a PT-111 with 37 rounds, and a .357 snub-nose revolver with 15 rounds, and I think we can successfully hold off half a dozen armed men.
But if the kick in the door and the family is scattered throughout the house as we usually are then I engage and try to buy my wife enough time to gather up the kids and make it to safety, whether that is the master bedroom our outside and who said you need to use a door to get outside? My wife is bright enough to bust out a window of whatever room she is in to escape.
As far as someone waiting outside to gun us down as we exit, it would be far easier and safer for them to throw a Molotov cocktail at the house and shoot us as we flee a burning house.
