In the United States, a gun show is an event where promoters generally rent large public venues and then rent tables for display areas for dealers of guns and related items, and charge admission for buyers. The majority of guns for sale at gun shows are modern sporting firearms. Approximately 5,000 gun shows occur annually in the United States. Venues and attendance Gun shows are typically held in large public facilities such as arenas, fairgrounds, civic centers, and armories. Show promoters charge vendors fees for display tables (from $20 to $145) and booths (from $200 to $400) and charge admission fees (from $5 to $50) for the public. In addition to guns, ammunition, knives, militaria, books and other items are sold. In 2005, Michael Bouchard, Assistant Director/Field Operations of ATF, estimated that 5,000 gun shows take place each year in the United States. Most gun shows have 2,500 to 15,000 attendees over a two-day period. The number of tables at a gun show varies from as few as fifty to as many as 2,000.

In 1999, the ATF reported that 4,442 gun shows were advertised in 1998 in Gun Show Calendar. SHOT Show The largest gun show in the United States is the annual SHOT Show. Only trade professionals, such as buyers for retail stores or law enforcement agencies, are allowed entry. It has attracted over 60,000 attendees to its 630,000 square feet of exhibition space in Las Vegas. The show is sponsored by the National Shooting Sports Foundation, an industry group of firearms and hunting businesses. It is among the top 25 trade shows in the country. Restrictions Under the Gun Control Act of 1968 (GCA), firearm dealers with a Federal Firearms License (FFL) were prohibited from doing business at gun shows (they were only permitted to do business at the address listed on their license). That changed with the enactment of the Firearm Owners Protection Act of 1986 (FOPA), which allows FFLs to transfer firearms at gun shows provided they follow the provisions of the GCA and other pertinent federal regulations. In 1999, ATF reported that between 50% and 75% of the vendors at gun
