Misconduct Involving Weapons (MIW) in Arizona is a broad criminal offense defined under Arizona Revised Statutes § 13-3102. It includes a range of prohibited conduct involving firearms or other deadly weapons, from unlawful possession to more aggravated acts like supplying a weapon to a prohibited possessor or using a weapon in the commission of another crime.
Many people equate MIW with felony gun possession, but the statute is broader. Felony gun possession typically refers to possessing a firearm when the individual is legally prohibited from doing so, such as after a prior felony conviction or other disqualifying status. However, MIW also includes situations involving prohibited weapons, unlawful transfers, and weapons use in furtherance of other crimes.
Depending on the circumstances, most felony gun possession charges are obviously felonies under Arizona law — though some are misdemeanors. The precise level of felony that a felony gun possession offense is charged as depends on the facts of the case, the type of weapon and the status of the individual accused. A.R.S. § 13-3102 contains a lengthy list of activities under the heading of misconduct involving weapons.
While many violations of this statute constitute a felony in Arizona, others are only misdemeanor violations. Pursuant to A.R.S. § 13-3102, the following offenses are misdemeanor gun and weapon possession offenses under Arizona law.
Simple possession of a deadly weapon on school grounds;
Failing to accurately answer a law enforcement officer when asked if a person is in possession of a concealed deadly weapon;
Entering a public establishment with a concealed deadly weapon after a request by the operator of the establishment not to possess weapons on the premise.
The extent of a felony gun possession sentence that a person may face depends on the charges and the facts. It is also important to note that the most common form of felony gun possession occurs when a person is in possession as a prohibited possessor. In these cases, probation is often no longer available, and the person may be facing a much longer felony gun possession sentence.

In addition to it being illegal to possess a firearm under certain circumstances by certain people under A.R.S. § 13-3102, certain items are banned entirely under Arizona law. These items are known as prohibited weapons and manufacturing, possessing, transporting, selling or transferring them constitutes a Class 4 Felony under Arizona law. Pursuant to A.R.S. § 13-3101(A)(8) prohibited weapon include any of the following:

Pursuant to ARS § 13-3101(A)(7) prohibited possessor means any person:
A deadly weapon as defined by A.R.S. § 13-3101(A)(1) means any weapon designed for lethal use, with the exception of a pocketknife.
Deface pursuant to A.R.S. § 13-3101(A)(2) means to remove, alter or destroy the manufacturer’s serial number
