"McMillon to associates: Our next steps in response to the tragedies in El Paso and Southaven," 3 Sept 2019

We’ve previously made decisions to stop selling handguns or military-style rifles... [W]e’re sharing the decisions we’ve made that go further:

• After selling through our current inventory commitments, we will discontinue sales of short-barrel rifle ammunition such as the .223 caliber and 5.56 caliber that, while commonly used in some hunting rifles, can also be used in large capacity clips on military-style weapons;
• We will sell through and discontinue handgun ammunition; and
• We will discontinue handgun sales in Alaska, marking our complete exit from handguns.

... [W]e are [also] respectfully requesting that customers no longer openly carry firearms into our stores or Sam’s Clubs in states where “open carry” is permitted – unless they are authorized law enforcement officers... As an additional step, we commit we will work alongside other retailers to make the overall industry safer... [W]e encourage our nation’s leaders to move forward and strengthen background checks and to remove weapons from those who have been determined to pose an imminent danger.
