One of the safest and deadliest tools available to the common man, firearms have proven to be protective in times of need and deadly in between hands of criminals. A new bill, House File 163, aims to limit the ability of criminals to commit crimes by limiting the maximum amount of ammunition a magazine can hold. Due to the seriousness of the topic, many Iowans agree that limiting magazine sizes and gun use is the solution, while others argue that it is unconstitutional and will prevent law-abiding citizens laws to protect themselves. With the passage of Iowa House File 163, Iowa would no longer allow magazines with a capacity greater than ten rounds, which is supported and opposed by almost equal numbers of Iowans. In opposition to magazines capable of holding ten or more rounds, a bill was introduced in the Iowa House of Representatives proposing to "prohibit the sale or transfer of high-capacity ammunition feeding devices" ( House File 163). Considered extremely dangerous, high-capacity magazines that hold up to hundreds of rounds increase a shooter's ability to quickly injure and kill large numbers of victims because they allow the individual to fire continuously without need to recharge (Law Center). In the United States alone, more than half of all public shootings involved the use of a magazine holding more than ten rounds (Follman). During the Sandy Hook school shooting, when Adam Lanza, armed with an AR-15 assault rifle and thirty-round magazines, stopped to reload his gun, eleven children were able to stand safe, avoiding the unfortunate fate of twenty of their classmates and six of their teachers (Council).
