The answer depends on what you mean by “dangerous.” A single rifle round delivers far more destructive energy to the body than a handgun round, making rifle wounds significantly harder to survive. But handguns kill far more people every year in the United States, simply because they’re involved in the vast majority of shootings. Both weapon types pose serious risks, but they pose different kinds of risk in different contexts.
What a Bullet Does to the Body
The core difference between handgun and rifle wounds comes down to energy. A standard 9mm handgun round carries about 342 foot-pounds of muzzle energy. A 5.56 NATO rifle round, the type fired by an AR-15, carries roughly 1,196 foot-pounds. A .308 Winchester hunting rifle round delivers around 3,009 foot-pounds. That means even a modest rifle round hits with more than three times the force of a common handgun round, and a full-size rifle cartridge delivers nearly nine times more.
That energy gap translates directly into tissue damage. When a high-velocity rifle bullet enters soft tissue, it loses gyroscopic stability and begins to tumble. The 5.56 NATO round, for example, fragments shortly after impact, rapidly transferring its kinetic energy into surrounding tissue and creating a large temporary cavity, sometimes called a “blast effect.” This cavity can reach 15 to 25 centimeters in diameter in the torso. Muscles, tendons, blood vessels, and organs well beyond the bullet’s direct path get torn and crushed.
A 9mm handgun bullet behaves very differently. It tends to maintain its stability as it passes through tissue, punching a narrower, more predictable wound channel. It still causes serious injury, fracturing bone and damaging soft tissue along its path, but it doesn’t produce the same explosive cavity that shreds surrounding structures. In practical terms, a person shot once in the abdomen with a rifle faces a fundamentally different surgical situation than someone shot in the same spot with a handgun.
Survival Rates Favor Handgun Victims
Clinical data confirms what the physics would predict. A study published in JAMA Network Open examined gunshot injuries from criminal assaults in Boston and found that caliber alone significantly changed the odds of dying. Compared to small-caliber firearms, medium-caliber guns increased the odds of death by 2.3 times, and large-caliber guns increased them by 4.5 times, even when the number and location of wounds were the same. The researchers estimated that if every shooting in their dataset had involved a small-caliber gun instead, gun homicides would have dropped by nearly 40%, with no change in how many people were shot or where they were hit.
That study focused mostly on handgun calibers, since rifles were nearly absent from the dataset (only one homicide involved a rifle round). But the energy gap between even a large handgun and a standard rifle is enormous, so the lethality advantage of rifles per individual wound is even more pronounced than these numbers suggest.
Handguns Cause Far More Deaths Overall
Despite being less lethal per shot, handguns are responsible for the overwhelming majority of gun deaths in the United States. They’re concealable, widely available, and present in most interpersonal violence. In one analysis of unintentional and undetermined firearm deaths, 81% involved handguns. In studies of mass shootings, handguns appeared in about 79% of events. Rifles were present in roughly 19% of mass shootings, and only 7% of those events involved an assault-style weapon exclusively.
This pattern holds across nearly every category of gun violence: homicides, suicides, accidental deaths, and domestic incidents. Handguns dominate the statistics not because they’re more powerful, but because they’re more accessible and more commonly owned for personal protection. Their small size makes them easy to store, carry, and, unfortunately, misuse.
Mass Shootings Tell a Different Story
When rifles do appear in mass shootings, the casualty counts tend to climb. Events involving assault-style weapons produced a median of 6 deaths and 6 nonfatal injuries, compared to a median of 5 deaths and 2 nonfatal injuries in events without them. Those medians may look similar, but the upper range diverges sharply. The deadliest mass shootings in U.S. history, events with dozens of casualties, have disproportionately involved rifles. A rifle’s higher rate of fire, larger magazine capacity, greater accuracy at distance, and more devastating wound profile all contribute to higher body counts in these scenarios.
Rifles are effective at ranges where handguns become nearly useless for most shooters. A handgun is designed for close-quarters use, typically within 25 yards or less for an average person. Rifles can accurately engage targets at hundreds of yards, giving a shooter the ability to inflict harm from positions that are harder for bystanders or responders to reach.
Overpenetration and Bystander Risk
One common assumption is that rifle rounds are more dangerous to bystanders in a home because they penetrate more walls. Testing by the U.S. Concealed Carry Association found that both weapon types penetrate far more building material than most people expect. Standard 9mm and .45 ACP handgun rounds passed through at least six interior walls of drywall. A 10mm handgun round went through more than ten. The 5.56 rifle round penetrated nine walls and showed the most bullet deformation, tumbling and creating larger holes as it passed through successive panels.
Neither type is safe to fire in a home with other people nearby. The rifle rounds did deform and fragment more, which in some configurations can cause them to lose energy faster than a handgun round that stays intact. But the raw penetration numbers make clear that any centerfire round, whether from a pistol or a rifle, will easily pass through multiple rooms of a typical house.
Two Different Kinds of Dangerous
Rifles are more dangerous per trigger pull. They hit harder, destroy more tissue, and are more likely to kill with a single wound. They’re also more effective at range and more devastating in mass casualty events. Handguns are more dangerous in aggregate. They’re involved in roughly four out of five gun deaths, they’re the primary weapon in homicides, suicides, and accidental shootings, and their portability makes them the firearm most likely to be present in a moment of crisis or impulse. If you’re thinking about this question in terms of public health, handguns are the bigger problem by volume. If you’re thinking about it in terms of what a single weapon can do to a single person, rifles are considerably more lethal.
