Handi rifle with 12 gauge barrel 5.5 lbs
Garand 11 lbs

Remember that classic dangerous game rifles were double barrel,
though many use bolt actions now due to cost.
Few use semi's, save for the occasional brown bear hunter.
A single shot should do well for many survival uses.

Handi rifles can switch barrels in a couple of minutes.
Run out of ruski ammo, trade barrels and shoot 223 ,30-06,
410, 357 etc.

Loaded for Bear, take a 35 Whelen barrel. Want to practice with the same weapon, use a 223 barrel and save money and reduce flinching.

Very easy to clean, you just take off the barrel.
Price is right-$200, keep one in each car. They break down to
2' or so.

Not what I would want in Iraq, but would be plenty happy with
one in say the backcountry of Canada.

I use one for deer and turkeys
when approaches are by mountain bike. I like the light weight, short
length, and low cost in case of crashes.
