Results: More shots were fired in attacks with pistols (average = 3.2 to 3.7) than in attacks with revolvers (average = 2.3 to 2.6). Methods: Using police records on fatal and non-fatal handgun assaults, t tests and χ 2 tests were employed to determine if attacks with pistols result in more shots fired than those with revolvers, leading to more gunshot victims and more severely wounded victims. Setting: Jersey City, New Jersey from 1992 through 1996. Many other modern firearms, including handguns, have rifled barrels more precisely, a rifle is a long-barreled gun with such grooves.Objective: To examine whether gun assaults committed with semiautomatic pistols are more injurious and lethal than those committed with revolvers.

The article also defined a rifle as a firearm with grooves on its barrel walls. 18, 2012: This article originally stated that grips and mounts can modify the power of a semi-automatic gun (they modify the ease of use) that machine guns are mounted to a wall or rail (they often are, but not always) that a pistol is a firearm with a single, nonrevolving chamber (some pistols are, but not all) that no revolvers are semi-automatic (none are fully automatic) and that James Holmes bought his weapons on the Internet (he bought his ammunition on the Internet). In the Aurora shooting, James Holmes used an AR-15 which he had purchased legally from gun stores and ammunition that he had purchased on the Internet.* Certain models were proscribed under the 2004 ban, but myriad loopholes allowed slightly modified versions of the gun to be sold legally. His mother, Nancy Lanza, acquired the gun legally. Lanza’s specific model was a Bushmaster M4 Type Carbine, using several magazines of 30 bullets each. Rifles can be single action, semi-automatic, or fully automatic.*ĪR-15: The semi-automatic rifle Adam Lanza used as his primary weapon.

Rifle: Long-barreled firearms with a groove carved into the barrel walls to give bullets spin.
