Relating to the creation of certain criminal offenses concerning firearm sales at gun shows.

HB 268 requires background checks for firearm sales at gun shows in Texas. It defines "gun shows" as events with three or more vendors charging fees, and mandates that sellers conduct federal background checks before completing sales and maintain sales records. Gun show promoters must notify local law enforcement 30 days in advance and ensure background checks are completed for all sales, with exceptions for peace officers and licensed handgun carriers. Violations are classified as Class A misdemeanors for sellers and promoters who fail to comply. The bill directly affects gun show sellers, promoters, and attendees purchasing firearms at such events.
