A month after 22 people were fatally shot at a Walmart in El Paso, Texas, the retailer is requesting that customers refrain from openly carrying guns into its stores.
Walmart is also asking customers not to carry firearms in stores in states with "open carry" laws unless they are authorized law enforcement officers.
Walmart will stop selling short-barrel rifle ammunition such as the.223 caliber and 5.56 caliber after clearing current stock.
On Tuesday, McMillon said that Walmart's changes to ammunition policies will reduce its market share from around 20% to between 6% and 9%. McMillon went on to say the policy changes were in response to last month's shootings in OH and Texas.
Walmart attempted again to balance customers who own guns and are "part of our customer base" with safety in stores, Dan Bartlett, Walmart executive vice president of corporate affairs, said on a call with reporters.
He says Walmart will continue to treat "law-abiding customers with respect" and it will have a "non-confrontational approach".
The latest shootings in August reignited the media and Democratic Party's push for gun control.
For years Walmart has been called the biggest gun dealer in the U.S. Bullock wants the program to be optional.
Walmart has however resisted calls to completely halt gun sales. "Congress and the administration should act".
McMillon stated that he was sending letters to the White House and the Congressional leadership encouraging them to implement stronger background checks and the removal of weapons from those "who have been determined to pose an imminent danger". The company said Tuesday that it would explore sharing its proprietary gun-sales technology platform with other retailers.
Two deadly shootings in Walmart's stores have pressured the nation's largest retailer to alter its gun-sales policies. "We do not sell military-style rifles, and we believe the reauthorization of the Assault Weapons ban should be debated to determine its effectiveness".
In the aftermath of the El Paso shooting, Walmart ordered workers to remove video game signs and displays that depict violence from stores nationwide.
Walmart has made decisions to scale back its gun and ammunition offerings before.
Senator Kamala Harris, asked if Walmart should stop selling guns, replied, "Yeah, I do.it's not that everyone needs to stop selling guns, but there need to be checks and balances". "We know these decisions will inconvenience some of our customers, and we hope they will understand". "This weekend brought tragedy to Midland and Odessa, Texas".
