Walmart is discontinuing the sales of certain types of guns and ammunition after two mass shootings at stores this summer. The retail giant announced it would no longer sell short-barrel rifle ammunition, and would halt handgun ammunition and sales in Alaska entirely.

At the same time, Walmart is also asking customers to no longer carry open firearms in stores where it is legal to do so, but it will not be changing its policy for concealed carry. CEO Doug McMillon says management has been listening to people in and outside of the company and “it is clear that the status quo is unacceptable.”

The announcement comes after two deadly mass shootings occurred at a Mississippi Walmart in July and an El Paso Walmart in August. And if you’re wondering about the “Walmart connection?” According to reports, one in five of the bullets used in major shooting incidents were purchased at through the chain.
