Louisiana is a "shall issue" state for concealed carry. The Louisiana Department of Public Safety and Corrections shall issue a concealed handgun permit to qualified applicants, after performing an NICS background check and giving the local police 10 days to provide additional information about the applicant. An applicant must demonstrate handgun proficiency by taking a training course from an approved instructor, or by having been trained while serving in the military. Concealed carry is not permitted in any portion of the permitted area of an establishment that has been granted a class A-General retail permit, to sell alcoholic beverages for consumption on the premises, or in any place of worship, government meeting place, courthouse, police station, polling place, parade, or in certain other locations.[3][4][5]

Open carry of firearms in Louisiana is permitted without a permit, as long as the user is of at least 17 years of age and legally able to possess a firearm under state and federal law.[6]

Louisiana has state preemption of firearms laws, except for local laws passed before July 15, 1985. Government bodies other than the state may not sue firearms manufacturers, dealers, or trade associations for damages that are the result of lawful activities.

Missouri Statute 571.070 (8/28/2007) says that it is unlawful for a felon or adjudged incompetent Person to have possession of any firearm (including concealable firearms). Violation of this law is a class D felony.[5] This law was the subject of a challenge, in which a nonviolent felon successfully argued that the law is unconstitutional as applied to him. The law failed muster against the required strict scrutiny test.[6][7] However, the law was found to be constitutional by the Supreme Court of Missouri.[8]

Missouri law exempts the possession of antique firearms, as defined in 18 U.S.C. Section 921, from the provision that specifies a person commits the crime of unlawful possession of a firearm if he or she is a convicted felon possessing a firearm.[5]

Missouri Statute 571.121 (8/28/2007) says that: (a) You have to carry your permit with you when you carry the concealed weapon, and if you don't have it with you, it is not a crime, but you can be fined up to $35; and that (b) County sheriffs issue a state CCW I.D. that reflects that you can carry concealed.[9]

In September 2014, Missouri lawmakers passed SB 656 allowing specially trained school employees to carry concealed guns on campuses. It also allows anyone with a concealed weapons permit to carry guns openly in cities or towns with bans against the open carrying of firearms. The age to obtain a concealed weapons permit was also dropped from 21 to 19 [See 2014 Senate Bill 656]. Missouri became the 10th state to pass legislation allowing armed school employees since the mass shooting at Sandy Hook Elementary School in Newtown, Connecticut, in 2012.[10] The bill was initially vetoed by Gov. Nixon, but the Missouri legislature overrode the veto during the September veto session.[11]

In September 2016, another Senate bill coincidentally numbered SB 656 was passed allowing permitless concealed carry by anyone 19[12][13] years of age or older who may lawfully own a gun. This bill was also vetoed by Governor Nixon, on June 27, 2016. After the Missouri legislature reconvened for the veto-override session on September 14, 2016, the Senate voted to override the veto with a 24 – 6 vote (23 required) and the House followed through shortly thereafter with a 112 – 41 vote (109 required). The permitless carry provision of the bill went into effect on January 1, 2017.[3]

The Constitution of Alabama provides that every citizen has a right to bear arms in defense of himself and the State. The State preempts local regulation of firearms. The firearm preemption statute reads "The purpose of this section is to establish within the Legislature complete control over regulation and policy pertaining to firearms, ammunition, and firearm accessories in order to ensure that such regulation and policy is applied uniformly throughout this state to each person subject to the state's jurisdiction and to ensure protection of the right to keep and bear arms recognized by the Constitutions of the State of Alabama and the United States." Localities may regulate the discharge of firearms and levy taxes.[1][2] On April 21, 2010, Gov. Bob Riley signed House Bill 2 into law as Act 2010-496 amending Ala. §13A-11-63, to allow civilian ownership of short-barrel rifles and short-barrel shotguns, as allowed by federal law.[5] The only firearms known to be prohibited are those disguised as walking canes.

Licensed dealers are required to process background checks through the FBI prior to completing a sale. Licensed dealers must keep a record of every handgun sold, including the purchaser's signature and particular information about the firearm being sold. Private sales of handguns and long guns are legal and no background check is required; however, it is unlawful to sell a firearm to a prohibited person.[1][2]

Firearms are prohibited from certain places, including demonstrations. Possession of firearms is prohibited on the premises of public schools by persons with intent to do bodily harm and those who do not have an Alabama Pistol Permit. Open carry on foot is generally allowed without a license, withstanding other applicable laws. As of Aug. 1, 2013, transportation of an unloaded handgun in a vehicle is allowed without an Alabama Pistol Permit if you are legally permitted to possess the handgun, and the handgun is locked away from immediate reach of all passengers. Carrying a handgun on premises that are not owned or under the control of the possessor is prohibited unless the person has a valid concealed handgun license.[1][2]

Gun laws in Illinois regulate the sale, possession, and use of firearms and ammunition in the state of Illinois in the United States.[1][2]

To legally possess firearms or ammunition, Illinois residents must have a Firearm Owners Identification (FOID) card, which is issued by the Illinois State Police to any qualified applicant. Non-residents who may legally possess firearms in their home state are exempt from this requirement.

The state police issue licenses for the concealed carry of handguns to qualified applicants age 21 or older who pass a 16-hour training course. However, any law enforcement agency can object to an individual being granted a license "based upon a reasonable suspicion that the applicant is a danger to himself or herself or others, or a threat to public safety". Objections are considered by a Concealed Carry Licensing Review Board, which decides whether or not the license will be issued, based on "a preponderance of the evidence". Licenses issued by other states are not recognized, except for carry in a vehicle. Open carry is prohibited in most areas. When a firearm is being transported by a person without a concealed carry license, it must be unloaded and enclosed in a case, or broken down in a non-functioning state, or not immediately accessible.

There is a waiting period to take possession after purchasing a firearm — 72 hours for a handgun, or 24 hours for a rifle or shotgun. For private sales, the seller must verify the buyer's FOID card, and keep a record of the sale for at least 10 years. Lost or stolen guns must be reported to the police. Possession of automatic firearms, short-barreled shotguns, or suppressors is prohibited. Possession of short-barreled rifles is permitted only for those who have an ATF Curios and Relics license or are a member of a military reenactment group. The state does not restrict the sale or possession of firearms that have been defined as assault weapons, or of magazines that can hold more than a certain number of rounds of ammunition, but some local jurisdictions do restrict them.

Illinois has state preemption for certain areas of gun law, which overrides the home rule guideline in those cases. Some local governments have enacted ordinances that are more restrictive than those of the state in areas not covered by state preemption.

On April 4, 2013, the Maryland General Assembly approved legislation imposing significant new restrictions on gun ownership. The bills ban the sale of certain semi-automatic firearms that they define as assault weapons, limit magazine capacity to ten rounds, require that handgun purchasers be fingerprinted and pass a training class in order to obtain a handgun license, and bar persons who have been involuntarily committed to a mental health institution from possessing firearms. Martin O'Malley Governor at the time, signed the legislation into law on May 16, 2013.[13] Regarding ten round magazine limits for rifles purchased in Maryland, 'standard' 30 round magazines may be purchased outside Maryland and brought into the state for personal use. Those standard magazines may not be transferred, given, sold or manufactured inside Maryland.[14]

As of October 1, 2013, detachable magazines for semi-automatic handguns and semi-automatic centerfire rifles which are capable of holding more than 10 rounds may not be purchased, manufactured or sold, though they may be possessed (but not transferred within the state) by persons who already owned them prior to enactment of the 2013 changes. Magazines greater than ten (10) rounds may be purchased or acquired outside the state and carried into Maryland and used within the state. Certain pistols are classified as "assault pistols", and banned from ownership if not registered prior to August 1, 1994.[2] Only handguns on the official handgun roster[15] may be sold in the state. Private sales of "regulated firearms," which includes handguns, are permissible, but must be done at a local Maryland State Police barracks. As of 1 Oct, a Handgun Qualification License (HQL) is required for the sale, as well as a background check and a mandatory seven-day waiting period. A person must obtain a safety training certificate prior to purchasing "regulated firearms" and present that certificate prior to each purchase. With some limited exceptions,[16] only one "regulated firearm" may be purchased in any 30-day period. Handguns manufactured on or before December 31, 2002 must be sold or transferred with an external safety lock. Handguns manufactured after December 31, 2002 may only be sold or transferred if they have an internal mechanical safety device.[3][4]

Firearms advocates challenged the 2013 law. The District Court ruled that the law was constitutional based on intermediate scrutiny. On February 1, 2016, the United States Court of Appeals for the Fourth Circuit overruled the reasoning used to uphold the law in a 2-to-1 vote. The appellate court said that the ban on semi-automatic weapons and high-capacity magazines should be subject to strict scrutiny, not intermediate scrutiny, because they "are in common use by law-abiding citizens." The court acknowledged that the state has a right to limit the use of or ban citizen possession, sale, or transfer of "dangerous and unusual" weapons (such as hand grenades), but the weapons and ammunition barred by the 2013 law did not fall under that provision. The appellate court remanded the case to a federal district court, leaving the ban temporarily in place pending a review by the district court. The state said it would appeal the decision.[17][18] On March 4, 2016, Fourth Circuit agreed to rehear the case en banc and oral arguments took place on May 11, 2016.[19][20] The full court ruled that such assault weapons and magazines holding more than 10 bullets are not protected by the Second Amendment; the Supreme Court refused to hear the case.[21]
