I don't live in a sprawling mansion with narrow hallways.
This is a reality for most people - most meaning 99.99%.
A rifle will never handle as fast and short as a handgun, not counting any AR/AK pistol as a handgun. For in-home distances, a rifle doesn't offer a real precision advantage over a well practiced handgun either. So if you really want fast handing in close quarters, you're not looking at a long gun. The fact tactical operators use SMG's and carbines and clear houses in teams doesn't have much bearing for a guy who wakes up to someone stealing his TV in the middle of the night. Teams have the advantage of directional effect as the TEAM enters and flows through a building, individuals don't have someone covering their tail in that manner, so the rules for the direction of fighting change. If someone breaks into my basement window (view out, ground level, only way into that side of the house), by the time I get down there, there are 4 rooms to clear - with my back exposed to 2 of them if I clear the other 2 first and vice versa... My likelihood to need to pivot quickly is much greater than a sweeping team, where a lead would cover forward and members behind would clear each room - sweeping forward for THEIR rifle. The Team's back should never be exposed, but an individual doesn't have that advantage.
Even in the event you're using a long gun in the house, if you're trained to be effective with a long gun, the length doesn't matter much anyway when you're talking 25" vs. 35". No matter how short a rifle might be, it'll never be effective if you're standing side by side in a 36"-48" wide space with your target - you're too damned close. So in reality, if your body fits in the space, your rifle fits. You're not a helicopter, you don't need 360* rotor clearance to make a 180* turn with your rifle. Muzzle down, muzzle up, and you're facing 180* from where you started, even in a 20" wide hallway. Honestly works the same way with a pistol - you are not a helicopter - if you're turning 180*, either muzzle down, muzzle up, or back into high compressed and back out, nobody should be turning around with their rifle shouldered and level or their pistol extended and level...
