Realistically, there would be no human element to worry about. One would be in a remote area. I live in lion country and have never had to worry about them except once one came after my horses. They are not hard to kill and about anything will do it. Coyotes are not a problem. I would be concerned about bear (thick on the Oregon coast but usually timid), Griz if further North and Moose which are maybe the worst of the lot. I am unfamiliar with wolves although saw my first in Oregon 6 hunting seasons ago. I would want a flinter which would be handiest for fire making, the most immediate and normal survival issue. I like 45 cal which is good for hunting and not a big waster of powder or lead. I would use the smallest diameter barrel for the caliber to keep the weight down. I also always carry small fishing equipment so food is likely less of a problem. Fishing is likely the easiest source of protein in most cases. If you are FAR up North, there is maybe a 6 week window for food gathering, otherwise, you had better be able to hunt, trap, and fish...and know what parts you MUST eat to stay healthy. Also knowing what to look for to identify sick game is important. rabbits, hares...stay away from eating those with spotted livers.
Any agate or jasper is a hardness of 7 and a good source of "flint". Heat it in a fire and it is easier to knap. Keep the flint TIGHT. Don't forget hatchet and multi-tool and proper clothing. Frankly, fishing is likely the best source of protein and coastal regions the best to stay well fed as crab and clams and birds are handy and berries are available for a couple months. You can get fat on the coast. Knowing what plants are edible is a plus. For berries remember white never, red sometimes, black always.
