Ok, I'm here again. This is the loadout:

Total weight: 7.14 kilograms in the screen, but the PA3 was not counted. I suppose it weights some 2.5 kilos, so make that around 9.5kg, +0.125 from bandages, +0.33 from cola can = ~10kg.
Franchi PA3/225: The big gun, for close quarters combat. I'm hoping on not needing this, as it should serve as a last resort against hostile punks. Most of my human interaction should ideally be trading with friendly settlements. The one I'd use most would be the Colt M1908, a lightweight, short pistol. I'm also taking ammo for both: A box of shotgun rounds for the Franchi and two small boxes of .25 for the M1908.
Urban vest, bonnet and gas mask would be the rags over my body. I don't suppose the gas mask would have much use, but it also has the intimidation factor.
A couple of bags, water, a pot, a multi-tool, phone(to communicate with other survivours) and ropes, besides a small knife. Those are the general utilities. Also, a battery pack, to keep everything running.
Passport and money. It is unlikely that there would be a complete collapse of government, and quite a lot of settlements will likely continue accepting old-world money.
Flashlight/glowstick, matches, a spare gas mask filter, binos, wristwatch and compass: More general utilities for surviving while alone and finding other people.
A book for keeping notes. Will serve to help keep myself sane, remember who I am and why I'm here.
MRE and beef jerky serve as food, I also put a cola can but I accidentally removed and just noticed now. Colas have a high content of sugar, so they would serve to give me an energy boost, and besides, it is not going to be fat or sugar that is going to take me down. A bullet to the neck is more likely.
And that is why I'm taking antibiotics and painkillers. Forgot to add bandages, tho.
Now that I have taken another look at it, I could have thrown away the middle bag. It's contents would easily fit into the backpack.
