>>1334454for just self defence with a good ability to draw fast use a kenai chest holster and pick a handgun based on what you could encounter. Such as minimum of 44mag hard cast for brown bear and moose, min of 357 for black bear, 10mm for wolves and mountain lions, 9mm hollow point for jamal.
If you want a multi purpose field gun just get a single shot break action 12 gauge and get a scabbard for your backpack slugs for big shit and 7 1/2 shot for small shit though 5 shot is nice for hare and ptarmigan
pic is what I carry in grizzly country. Its a ruger super redhawk toklat in 454 casull.
https://gunfightersinc.com/kenai-chest-holster/ this is the holster I use. It is worth every penny. I went through a bunch of cheap and not so cheap holsters before I bit the bullet and bought this one. Don't waste your money on uncle mikes holsters or alaskan backpackers holsters. they were $50 each and were hot trash. Just drop the $150 on a quality holster.
