Walmart will stop selling handguns and certain types of ammunition, and will no longer allow customers to openly carry firearms, after separate shootings at company stores last month left at least 24 people dead.

“It’s clear to us that the status quo is unacceptable,” chief executive Doug McMillon said in a memo to employees on Tuesday. “We know these decisions will inconvenience some of our customers, and we hope they will understand."

Walmart is set to end sales of handguns in Alaska and will discontinue the sale of short-barrel rifle and handgun ammunition in stores nationwide, the super chain's president and CEO announced Tuesday afternoon.

The store said it will gear its focus toward long barrel deer rifles and shotguns, supply much of the ammunition they require and provide hunting and sporting accessories and apparel, Doug McMillon wrote in a memo.

"We have a long heritage as a company of serving responsible hunters and sportsmen and women, and we're going to continue doing so," McMillon said.

Walmart on Tuesday announced major changes to its stance on ammunition sales, following two deadly and “horrific” shootings at Walmart stores over the summer.

The retailer is calling on the government to do more in the wake of a larger wave of mass shootings across the country, including one as recently as this weekend in Odessa, Texas.

Walmart is also asking customers at Walmart and Sam’s Club to no longer openly carry firearms in stores, in states where “open carry” is allowed, unless authorized law enforcement officers are present.
