Help me make a HD Gun decision.

Context: I live in an apartment.

At present, my home defense weapon is an S&W M&P 2.0 with an Plight Baldr light with some +p Hollow points. I am in MO, so a pretty darn free state.

The neighborhood I live in is not terrible, but it's getting worse.

I've been hemming and hawing over a more significant weapon for Home Defense.

I currently only have firearms in the current calibers:

5.56

9mm

12 GA

.22 LR

I have a couple of 16" ARs, a couple of Mossberg Maverick 88s, a Ruger 10/22, and four pistols in 9mm.

Here are what I've considered. The goal is to increase lethality on soft targets and minimizing over penetration,

AR pistol, 10.3", 5.56 with hollow points.

AR pistol, 8-10.3", .300 blackout with subsonic hollow points (if available)

I don't plan on canning my firearms at present. I dislike placing my name on a registry. I would also rather wake up the entire apartment complex to get as much assistance in calling 911 as possible.

Thanks in advance!
