As of 2019, Walmart was a major retailer of firearms and ammunition. In 2019, after 23 people were killed in a mass shooting at a Walmart store in El Paso, Texas, Walmart announced that it would stop selling all handgun ammunition and certain short-barreled rifle ammunition. The company also announced that it would stop selling handguns in Alaska, the only state where the company still sold handguns. The move was expected to reduce Walmart's U.S. market share in ammunition from around 20% to around 6–9%. Walmart also stated that it was "respectfully requesting" that customers not openly carry weapons in Walmart stores, except for authorized law enforcement officers.
