Walk 7 miles a day in remote area...whats a good handgun caliber to ward off coyotes. Two of them killed a girl here last fall while she was hiking. They are being seen alot and a friend was jogging last week and one came over the snowbank and was going to start at his legs. He fired a flare gun and wily coyote took off. I carry a flare gun, air horn and ww2 army short sword german. Never had a gun but they might get used to flares and air horns but they will not get used to a bullet. Looking for suggestions and comments please.....Thanks
