Waiting periods for the possession of firearms are a commonsense way to prevent impulsive, volatile acts of gun violence. 

A waiting period law requires a certain number of days to elapse between the purchase of a firearm and when the buyer can actually take possession of that gun. By delaying immediate access to firearms, waiting periods create an important “cooling off” period that can help prevent impulsive acts of gun violence, including gun homicides and suicides.


The immediate purchase and acquisition of a gun allows people to act on temporary emotions and impulses, which can increase the risk of both gun suicide and gun homicide.

  • Suicide attempts are often impulsive, singular episodes that involve little planning. Many studies suggest that most suicide survivors contemplated their actions for only a brief period of time—often less than 24 hours—before making a suicide attempt.1
  • Similarly, studies suggest that some of the factors that incite violence against others, such as anger and rage, can be short-lived.2

Waiting period laws, which create a buffer between the time of gun purchase and gun acquisition, can help to prevent impulsive acts of gun violence. In particular, studies suggest that waiting period laws prevent firearm suicides and firearm homicides.

  • Studies suggest that waiting period laws are associated with reduced rates of firearm suicide.3 By one estimation, waiting period laws may reduce firearm suicide rates by 7–11%.4
  • Waiting period laws also appear to reduce gun homicide rates. One study found that waiting period laws that delay the purchase of firearms by a few days can reduce gun homicides by roughly 17%.5

Waiting periods can also give law enforcement agencies additional time to complete background checks that sometimes cannot be completed within the three-day window provided by the federal law.

  • Each year, approximately 3,800 ineligible people acquire firearms through so-called “default proceed” sales,6 in which a dealer completes a sale without a completed background check after three business days, as is allowed under federal law. (For more information on this issue, see our page on Background Check Procedures.)
  • As a result, FBI experts have recommended extending the time to complete background checks to reduce the number of prohibited people—like people subject to domestic violence restraining orders—able to purchase firearms by default proceeds.7

Waiting periods are a popular policy supported by the overwhelming majority of Americans.

  • A 2019 study found that Americans routinely underestimate public support for gun safety measures including waiting periods: 85% of non-gun owners and 72% of gun owners support mandatory waiting periods for firearm purchases.8
  • Another poll from 2017, which asked participants about their support for a lengthy waiting period of 30 days, found that 75% of Americans favor a 30-day waiting period for firearm purchases9

Summary of Federal Law

There is no federal waiting period. Under the National Instant Criminal Background Check System (NICS), a dealer may transfer a firearm to a prospective purchaser as soon as he or she passes a background check.10 Generally, if the FBI is unable to complete a background check within three business days, the dealer may complete the transfer by default.11 However, if a person under age 21 tries to buy a long gun and NICS identifies a potentially disqualifying juvenile record for the person within this initial three business days, NICS has ten business days from when the FFL first contacted the system for a background to determine whether the person is disqualified from possessing a gun, after which time the dealer may complete the transfer by default.12

Federal law doesn’t require private sellers to perform background checks on gun purchasers. Accordingly, persons purchasing firearms from private sellers may take immediate possession of their weapons, unless state or local law provides otherwise.13

Summary of State Law

Thirteen states and the District of Columbia have waiting periods that apply to the purchase of at least some types of firearms.14 See our summary on Background Check Procedures for state laws that prohibit gun sales or transfers until a background check is completed.

It’s also important to note that some other states require gun purchasers to obtain a license or permit prior to the purchase. Because these licensing laws also generally prevent people from immediately gaining ownership of deadly weapons, they also include implicit waiting periods in many cases. See our policy page on Licensing for information about licensing laws.

States Imposing Waiting Periods for Purchases of All Firearms

  • California – 10 days15
  • Colorado – 3 days (Effective October 1, 2023)16
  • District of Columbia – 10 days17
  • Florida – 3 days or the time it takes to complete required background checks, whichever occurs later18
  • Hawaii – 14 days19
  • Illinois – 72 hours20
  • Maine – 72 hours21
  • New Mexico – 7 days22
  • Rhode Island – 7 days23
  • Vermont – 72 hours24

Fewer gun homicides because of waiting periods
Waiting period laws that delay the purchase of firearms by a few days can reduce gun homicides by approximately 17%.


Michael Luca, Deepak Malhotra, and Christopher Poliquin, “Handgun Waiting Periods Reduce Gun Deaths,” Proceedings of the National Academy of Sciences 114, no. 46 (2017): 12162–12165.

California, Rhode Island, Washington, and the District of Columbia impose a statutory waiting period on all firearm purchases. Subject to limited exceptions, California and the District of Columbia require a ten-day waiting period for all firearm purchases.26 Rhode Island imposes a seven-day waiting period for all purchases of firearms unless the purchaser is a law enforcement officer.27 Vermont has a 72-hour waiting period for purchases from dealers that do not occur at gun shows.28 However, in both Rhode Island and Vermont, the seller must deliver the firearm to the purchaser if, within seven days, they do not receive background check information disqualifying the potential buyer from purchasing the firearm.29 New Mexico imposes a seven-day waiting period for purchases of a firearm, unless the buyer holds a New Mexico concealed handgun license.30

In Hawaii, all firearm purchases require issuance of a permit, and no permit may be issued earlier than 14 calendar days after the date of the application.31 This does not include sales to state or federally licensed dealers, law enforcement officers, persons with a license to carry a handgun, or where a firearm is brought into the state and registered in accordance with the state’s registration statute.32 All permits must be issued or the application denied before the twentieth day from the date of application.33

In Illinois, it is unlawful for anyone to deliver a firearm prior to the expiration of the statutory waiting periods, which are currently set at 72 hours for handguns and long guns.34 Maine has a mandatory 72-hour waiting period for all gun purchases for which a background check is required, which includes sales from licensed dealers, advertised private sales, and sales at gun shows.35

Florida and Colorado have a mandatory waiting period between the purchase and delivery of any firearm sold by a licensed firearm dealer. The mandatory waiting period is either 3 days, excluding weekends and holidays, or the time it takes to complete the required criminal background check—whichever occurs later.36

States Imposing Waiting Periods for Certain Classes of Weapons

  • Minnesota – 30 days (Effective August 1, 2023, handguns and assault weapon purchases from dealers)37

Minnesota imposes a waiting period on transfers of handguns and assault weapons from licensed gun dealers from the day the dealer delivers a transfer report to the police chief or sheriff.38 The police chief or sheriff may waive part of the waiting period in writing if he or she finds that the transferee requires access to a handgun or assault weapon because of a threat to the life of the transferee or a member of the transferee’s household.39 The waiting period does not apply to transfers by private sellers.40

States Imposing Waiting Periods for Handguns Only

  • Maryland – 7 days41
  • New Jersey – 7 days42

In Maryland, any person who transfers a handgun must wait seven days from the time a prospective purchaser completes an application to purchase the firearm and the application is forwarded to the Secretary of the Maryland State Police.43

New Jersey prohibits retail firearm dealers from delivering a handgun to any person unless he or she possesses a valid permit to purchase a handgun and at least seven days have elapsed since the date of application for the permit.44 Since each permit is valid for only one handgun purchase, this effectively creates a seven-day waiting period for all handgun sales.45


We’re in this together. To build a safer America—one where children and parents in every neighborhood can learn, play, work, and worship without fear of gun violence—we need you standing beside us in this fight.

Key Legislative Elements

The features listed below are intended to provide a framework from which policy options may be considered. A jurisdiction considering new legislation should consult with counsel.

  • A waiting period is established for all firearm purchases, of sufficient duration to allow a cooling-off period prior to the purchaser taking possession of the firearm
  • Permits to carry firearms in public do not exempt a purchaser from the waiting period
  • Transfer of firearms is prohibited until the background check process has been completed, regardless of whether the waiting period has elapsed.46
