For my own use, which would probably not apply to others.
AR15. Probably 11.5 inch barrel.
Foxtrot Mike 9mm pistol with a 7 or 10 inch barrel
Hasn’t been made in a side loader yet, only tube fed, but still my choice. Henry 41 mag carbine.
One thing to consider is, you do not need to run a heater 24 hours a day. Only enough to heat the room, and then shut it off until the room gets cold and a sweater or blanket won’t keep you warm. Also, you can stay/sleep in the living room, and close all other doors to keep heat in only the rooms you need.
Also if you have the extra cash, buy a propane burner that runs off of the bottles, so as you cook, you are also heating the room.
I also line in an apt, tho it does not get as cold here as it does in MA. I also have a Coleman stove with a few gallons of fluid for cooking, some kerosene lamps, and candles. You can also do the candles and terracotta pot heater, but there is a fire hazard with any open flame, and one has to be concerned about a smoke detector going off as well.. I also have a 12 volt blanket and marine battery, and can charge the battery with my car if it runs down.
A generator would be great, but once started, you would have more friends than you thought you had.
I was looking at the Skywave SSB, but now they are coming out with a Skywave 2. Has new features that I think will be a big plus. $200 is a lot, but I think for what it is, it will be well worth it.
My current radios are Eton Elite 750, Tecsun PL-680, 380, and R9700X.
I have been out of listening for around 20 years, and getting back into it, things have really changed, and seems like a struggle to play catch up. So I am just going to keep things simple as much as possible. With all that’s going on in the world, I think alternate sources of information and news will be helpful if things go South.
