Establishes a waiting period before a firearm, shotgun or rifle may be delivered to a person

Extended the mandatory waiting period for rifle and shotgun transfers from ten business days to three calendar days.

Added a specific provision allowing licensed gunsmiths or dealers to immediately transfer pistols, revolvers, or semiautomatic rifles to other licensees upon receiving a 'proceed' response from the background check system.

Updated the background check process to explicitly include a three-day calendar wait for those without a valid license to purchase, carry, or possess a pistol, revolver, or semiautomatic rifle.
