Why do Handguns Appear more Effective in Stopping Bear Attacks than Rifles and Shotguns?

A surprising result of the research done to determine if handguns are effective when used in defense against bears is they appear to be more effective than rifles or shotguns. This is a surprise. Rifles and shotguns tend to be more powerful. They are easier to use accurately at a distance.  When expecting a bear encounter, the preferred firearm is almost always a high powered rifle or a shotgun.

Terms become very important in this discussion. Rifles and shotguns are better tools for hunting bears than most defensive handguns.

Hunting is not the same as defending.

Much of the advantage of accuracy at range of rifles and shotguns is eliminated because most defenses against bears occur at very close range. Defensive handguns have been designed with close range defense in mind. They are specifically designed for quick access, and repeated fast shots at close range.

In the study done by Herrero and Smith, Efficacy of Firearms  for Bear Deterrence in Alaska, in 2012, Herrero and Smith found handguns to be marginally more effective than long guns, with long guns at 76% effective and handguns at 84% effective. Herrero and Smith note, because of the small sample, this is not a statistically valid difference. The study includes many instances where a firearm was not fired, for various reasons.

One of the main reasons handguns appear to be more effective is because they are fired more often in defense against bears. Handguns are meant to be carried on the person, usually in a holster. Holsters are ergonomically designed and extensively tested to allow quick access during stress. The same holsters are designed to prevent the firearm from being lost during strenuous activity.

Rifles and shotguns are generally carried in the hands or on a sling. Most hunting slings are not designed for quick access. Many sportsmen carry their rifles and shotguns with an empty chamber. Many agencies require long guns to be carried with an empty chamber. Carrying a long gun on a sling tends to slow the response time by a second and a half to three seconds, if well practiced. Carrying with an empty chamber slows the response time by another three to five seconds, if well practiced. It is not difficult for most people to learn to draw and fire two aimed shots from a holster with a handgun, in under two seconds. If not well practiced, when a firearm is carried with an empty chamber, many try to fire the first shot, only to realize they have an empty chamber. This slows the response many more seconds. This information comes from a retired law enforcement firearms instructor with decades of experience, who did considerable testing. This does not apply to tactical slings, where the delay can be relatively small. Few people carry long guns in tactical slings.

Because rifles and shotguns are more cumbersome than handguns, they are often left some small distance from the person. Rifles are often leaned against a tree, a wall or a tent pole while chores are being done. They may be laid down on the ground, a rock, or on a tent floor. A significant number of times, a person with a handgun will have the handgun on their person while a rifle will be a few feet away. Because a long gun is more commonly left unsupervised, there is more incentive to leave the long gun with an empty chamber.

Once enough power is achieved for bullets to penetrate vitals and break bones, diminishing returns are encountered. The extra power and energy available from a rifle or shotgun may not make much difference. Even relatively low energy bullets hurt a great deal. The entire theory of bear spray is based on the notion of inflicting pain on the bear. If the bear experiences enough pain, it is likely to stop the attack.  Handguns have a larger capacity than most rifles or shotguns, so more shots can, to an extent, make up for lower power individual shots. Several shots from "low power" handguns deliver as much power as a single buckshot load from a shotgun.

Because bear defense usually occurs at very close range, handguns have an advantage. They are easier to hold onto in a deadly fight against a bear where contact occurs. Because of their length, long guns can be more easily knocked away from a person. In confrontations with humans, it is easier to disarm someone who has a long gun than someone who has a handgun, because the length of a long gun gives more leverage.  It is easier to hold onto a handgun with one hand than it is to hold onto a long gun with one hand.

Selection bias of what is considered an attack makes handguns appear to be more effective. 

Handguns, by their nature, tend to be used at very close range. If a long gun is used to deal with a bear at longer range, the bear is likely to be killed without any human injury. Those situations will seldom be classified or reported as a bear attack, or even as an aggressive bear. Bear problems solved at long range with a long gun are seldom recorded as successful defenses. Bear problems solved at short range, where handguns have advantages, are likely to be classified as a aggressive bear defense or a bear attack. In the Herrero and Smith literature, a bear attack is defined as when a bear makes physical contact with a human. Under this definition, all successful defenses against bears, where the bear is killed or driven off before physical contact occurs, are not considered bear attacks.

The two factors, better availability and accessibility to handguns during bear encounters and the selection bias in favor of defenses against bears with handguns are the reasons handguns appear to be more effective than long guns for defense against bears.

If people carried handy, high capacity long guns in tactical slings, with a loaded chamber, ready to deploy in a fraction of a second, as defense against bears, the results might be more effective than the 98% we see with handguns.
