"But user competency is the largest determining factor in the successful use of a firearm. “When a person is competent with firearms—and I mean competent under pressure —it is an effective deterrent I highly recommend,” he says. “Conversely, those with little to no firearm experience shouldn’t rely on a firearm to save them from a close encounter with a bear.”
He recommends
getting training if you intend to carry a gun. “However, even that same firearm-competent person would do well to carry bear spray also,” the researcher states. Smith highlights bear spray’s ease of use and portability as the reasons for that, as well as its effectiveness in nonlethal encounters."
IMHO the
average person who isn't proficient in firing powerful handguns is better off with bear spray. The victim in this thread probably wasn't a gun person.
Firstly, people have successfully defended themselves and others from large bears using 9mm pistols. Obviously those are not
ideal but it has been done. Repeatedly. So I'm not specifically advocating a "powerful handgun". Nor was I suggesting that the victim or anyone
should have had a handgun. Only that, from the original article, it seemed to me that a gun of some description may have proved more effective than bear spray. It does however appear, upon reading more detailed articles, that this is likely not the case due to how the attack actually happened.
Regarding training, and the recommendation in the article that anyone wanting to carry a gun for bear defense should get training: I don't think
training is necessary. I think learning to safely and effectively handle, present, and shoot a chosen firearm is necessary. As well as practice. How much and what kind of practice is necessary would depend entirely on the situation.
For example: If I am pulled out of my tent in the night and mauled by a bear, would practicing scenarios of shooting a charging bear be helpful? Probably not. But perhaps being able to shoot a handgun quickly at close range with only one hand would be helpful.
Another example: If I awake to find a companion in the next tend has been pulled from it and is being mauled by a bear, do I need to be able to aim my shots well enough to hit the bear without hitting the victim? Yes.
If a person can go to the square range, and shoot a gun at 21 feet and consistently hit a 12" target with some speed, they can help a person who is being mauled. Providing they have the will to try.
Is bear spray a good idea in Grizzly country? Yes. Is a gun a good idea in Grizzly country? Yes. Is knowing how to use each effectively important? Yes.
