CHARLESTON, W.Va. — Walmart Inc. announced Tuesday it will discontinue sales of short-barrel rifle ammunition, handgun ammunition and handgun sales in Alaska.

The news from the Bentonville, Arkansas company comes after multiple mass shootings in August, including one incident at a Walmart store in El Paso, Texas.

The company previously decided to stop selling handguns and military-style rifles — including the AR-15 — as well as raise the age limit to purchase a firearm and ammunition to 21.

Walmart Inc. is also asking customers to not openly carry firearms into Walmart and Sam’s Clubs locations where “open carry” is allowed unless they are an authorized law enforcement officer.

West Virginia is an open-carry state.

“As an additional step, we commit we will work alongside other retailers to make the overall industry safer, including sharing our best practices,” CEO Doug McMillon wrote to associates.

“For example, we are exploring ways to share the technical specifications and compliance controls for our proprietary firearms sales technology platform. This system navigates the tens of millions of possible combinations of federal, state and local laws, regulations and licensing requirements that come into effect based on where the firearm is being sold and who is purchasing it. We hope that providing this information, free of charge, will help more retailers sell firearms in a responsible, compliant manner.”

McMillon added lawmakers should strengthen the nation’s background check system and remove weapons from people “who have been determined to pose an imminent danger.”
