I like the 1911, but it's heavy and limited in capacity. I'm approaching 78 and ain't planning or able to bugout 'cause I don't have a remote cabin in the woods... or a bunker somewhere... or a vehicle that might run after an EMP or solar flare.
I would opt for my Glock 21 and have many mags and boolits for it. My Kahr P45 could be a backup. You definitely would want a popular caliber... 9mm or .45 for ammo availability, and .556mm, 7.62x39mm, or 7.62x51mm rifles for the same reason.
Everyone talks about bugging out to the woods and living off the land. Well good luck with that... you and 10's of millions of others will be vying for the soon scarce resources, and the worst will come out in most people... even the "good" ones when they and their family get hungry.
What is it... the HK 416, or something like that that's highly thought of as a dependable rifle. I keep seeing this in the novels. Glocks ar popular, too... 9mm's and .45's.
I have plenty of ammo for all of my guns and don't shoot anymore since COVID... just got out of the monthly practice. I still carry all of the time... even now at home, but it's my P380 and the night sights still work after 14 years! I got it 1 April 2010... and had to send it back to have the DOA front sight replaced. I was thinking that I needed new sights, but I can still see them across the room on my nightstand when I got to the bathroom at night. My G-21 and my wife's G-43 are close, too.
My usual carry of my Kahr P40 with ported barrel has become a carry-along in the car safe gun for trips as my shorts/pants got a bit tight and the P380 was smaller and more comfortable. That little pistol is always on my hip or by me at home... everywhere.
I hope that the S--- never hits the fan, but who knows with all of the illegal, invading "immigrants" which could include whole armies of Islamic and Chinese terrorists as well as just the MS-13 and other criminals, so keep your powder dry and stay prepared.
I have my PSA PA-10 with mags and ammo, and a nice PA-15 with much ammo, too, but don't plan on carrying anything.
My favorite genre for reading since I got Kindle Unlimited years ago is apocalyptic scenarios after EMP's, solar flares, or biological warfare attacks... or combinations of those... and earthquakes... fun reading.
Don't forget toilet paper and decent hiking shoes/boots... so much to think about... especially water purification and food preparation... keeping warm. Light decent body armor might be appreciated, too. My IIIA+ steel stuff weighs 23 pounds and isn't the easiest to put on, and I'm not hiking in that, either.
YMMV
