providing the OP's scenario took place with no shots fired, I would make NO attempt to restrain him physically. I'm not getting within 15 feet of him... even if he's proned out spread eagle on the floor, and I am standing on (one of) his weapon(s).
I am calling 911 on speaker. With the exception of the few 10th's of a second to dial... both of my hands are on my weapon, and it is always pointed at him... I am not taking my eyes off of him, nor my gun.
In a rural area I will have a bit of a wait... prolly 10 minutes or more. I will tell the dispatcher that when I hear sirens, I will explain to the dispatcher the best means of entry for the LEO to my house... I will not take my weapon off the intruder until the police have theirs trained on him or until I see the UNIFORM. LEO will be aware of this because it will be explained to the dispatcher. LEO needs to announce, because it could be an accomplice.
If I am not alone in the house (which is most likely) my wife will be making the call. She is armed at this point as well but out of the line of fire (of me and the first BG).
