TRH,
We're not talking battle in a war zone. We're talking one person trying to clear an urban/suburban home with a long gun. Believe me, it is very easy for a crook to take a long gun from a good guy. I've seen it done many times in training.
I would never attempt to clear my home with a long gun. It's a bad idea with potentially deadly consequences.
From what I've read, you simply trying to clear your home would be a bad idea with potentially deadly consequences.
And, yeah, I have done the "clear a building with a long gun" thing. I damn sure didn't wish I had a pistol when I did it.
