My POV is that the best advantage you can get in a home invasion is by being at the end of a hallway, in a prone position with most of your body being in a dark room, and your weapon pointing up at average head height for an adult male entering the other side of the hallway.
Primary weapon is a large magazine firing .22 LR. Secondary weapon is a .357 with hardened steel core bullets, which I believe is currently illegal to sell, if not to own, so is probably a home load.
Here’s the logic.
The tactical advantage to being low and having the enemy come to you is that you get a huge, relative advantage of ID’ing them prior to a head, chest or belt buckle shot; or combination thereof; whereas they first have to see you, then lower their weapon to your much reduced profile.
If they are the typical Juan Tyrone, .22 LR will only have about a 40% chance of dead-on-the-floor, but unless they get him to a hospital and pump him full of about 1,000,000 of penicillin, he will get the notorious “.22 peritonitis” with a high probability for his demise within a week or two.
Personally, as long as they are incapacitated and going to die, I don’t mind when they do it, so I’m not going to fuss with any one shot kill or over-penetration worries.
The secondary weapon is in case Juan’s smarter cousin, Pedro Remora, is smart enough to buy or steal some slightly used police body armor, typically type IIa or II. I don’t want to be limited to just head and leg shots, when I can dog tag him. No other reason for the policia to know about that gun or its rounds.
