Don't assume things pal, I happen to have hunted deer and javelina with a .44mag for years so I have no illusions about what a pistol can do and I doubt that you can out shoot me with a pistol anyways.
Where do you live that you can get all kinds of coyotes to walk to within 30 yards on a regular basis? It wasn't common for me in Yuma, north of Phoenix, or west of Salt Lake City where I did most of my hunting.
Regardless, my experience in Arizona has been that you hardly ever get coyotes in any closer than 100 yards, it happens but you'll wait a long time and miss a lot of yotes between shots.
First off, since I don't know you from Adam, you ain't my "Pal", altho we probably could be. Secondly I think it's hilarious that you tell me not to assume anything, yet in the same sentence, you immediately assume you can outshoot me with a handgun. Even if you can, it don't make you a handgun hunter and one does not have to assume this.
If you do hunt with a handgun, then you know that with a rifle, odds are you would have taken that shot long before the animal got into handgun range. No different than hunting Turkeys with a bow. Folks that have only hunted them with rifles think 75 yards is a close shot. Folks that hunt them with shotguns like them within 30 yards. With a bow, I like them to be within 15. I never knew how easy it was to get and keep a turkey within 10 yards of you until I started to hunt them with a bow. Until then, They were dead and on the ground before they reached the 20 yard marker. Very similar to bow hunting deer. Folks that never bow hunted probably are not used to shooting many deer under 15 yards away. The trigger is pulled long before they get that close. I think the same is true for 'yotes. Folks don't think they come within 50 yards because they've already taken their shot @ 100.
My point of this thread is not what is common shooting distances for you or for me. The point is that coyotes are not armor plated, nor are they hard to kill. Within it's limitations, a 9mm will do just fine. The problem that is very obvious here is that most folks are not comfortable with the limitations of a 9mm or even the use of any handgun for coyotes and it basically comes down to shot opportunities. Some folks want the most shot opportunities possible, even if they are low percentage and at long distances. To some folks fewer shot opportunities, even no shot opportunities are worth the effort, skill and patience it takes to get an animal into handgun or bow range. To them, it ain't about the kill but the hunt. To many, a hunt is not successful unless there is something dead in the back of the truck. To others the mere thrill of having an animal within 15-20 yards makes the hunt, regardless if a shot opportunity presents itself.
Ever fish Muskies? They say it is the fish of 10,000 casts. This is why only a few hardcores fish exclusively for them. To them, a single "follow" in a day's worth of casting 2 OZ plugs is a good day. For many tho, the thrill of catching twenty 2' Northerns in the same day, or a dozen 2# bass is what determines success. Neither are right or wrong, nor is one better than the other. They just have different priorities and different goals. Same could be said for shooting a 'yote with a handgun. Not every hunter can or will ever do it. For those that do and can it is an accomplishment to be proud of. That's what makes a handgun hunter.
