On Tuesday, Kroger followed Walmart by asking shoppers not to have weapons in any of their stores, in states where "open carry" is permitted, unless they are authorized law enforcement officers.
The announced changes come amid a wave of fatal shootings in the United States, including two in Walmart stores this summer.
Both companies are also asking the government to strengthen background checks.
"Kroger respectfully requests that customers no longer openly carry firearms into our stores, other than authorized attorneys," Jessica Adelman, corporate affairs director, said in an email statement. "We are also joined by those who encourage our elected leaders to pass laws that will strengthen background checks and remove weapons from those found to pose a risk of violence."
"A year ago, Kroger made the conscious decision to completely abandon firearms and ammunition when we stopped selling them in the Fred Meyer stores in the Northwest Pacific," she said, too. "Kroger has demonstrated with our actions recognizing the growing chorus of Americans who are no longer comfortable with the status quo and advocating for concrete gun reform and common sense reforms. "
After a shootout in Parkland, Florida, in 201[ads1]8, Kroger said that Fred Meyer stores would stop selling firearms to buyers under 21.
