I used to tent camp in remote places quite a bit. I carried a lightweight single shot 12 gauge shotgun with the buttstock lightened and shortened and the barrel cut to 18 inches. I carried standard 2 3/4 inch slugs for it. For two legged critters I kept a Glock 19 inside my sleeping bag in a when I slept. I swampy areas I carried a stainless steel S&W model 66 in 357 Magnum with adjustable sights, 125 grain JHP's and shot load cartridges for snakes.
Despite some media reports, there were no AK-47s involved in the incident
