How are you getting to your camp?If you will have beasts or wheels of burden,3lbs of handgun and 1 lb of ammo is no big deal.But it would pay 3 lbs toward a cot,and I'd prefer the cot.
If you are going to live out of a pack for a week and you are humping it to 9000 ft....I dunno.In one of those Oct/Nov storms,I'd rather have a 3 lb tougher tent,or some more stove fuel.A miox water purifier.A nylon backpacker bucket so you can get a couple gallons of water out of a stream without getting your boots wet.A machette in case I have to rely on firewood.
A handgun is way cool,but my rifle can multi-task (hunting and defense tool)
Lots of folks in serious conditions like ww2 carried only a rifle and more ammo instead of a sidearm.
High country hunting in Colo,it is even possible to run across a lion,wolves are in a few areas the very rare Grizzly,I suppose.I believe you are more likely to be confronted by extreme weather .
So,it all depends on your weight budget and priorities.
For me,my rifle,gps, map,compass,binoculars, water,knife ,food,walkie talkie,poncho,and one extra layer and a couple of battle dressings are quite enough to carry hunting.
But,thats me!!You have fun your way
Oh,on whacking bears in the faceI suppose you just have to be in the situation to understand.If you suddenly have a bear's face 2 feet from yours,whacking it might seem like the thing to do at the time.And,when I did it,the bear jumped back.Then I shot him
