Outdoor retailer L.L.Bean announced that it will no longer sell guns or ammunition to patrons under the age of 21, making it the fourth retailer to alter its policies since last month’s deadly school shooting in Parkland, Florida.

“In the wake of this shooting we have reviewed our policy on firearm sales, and we will no longer be selling guns or ammunition to anyone under the age of 21,” the company said Thursday in a Twitter response to customers.

Although L.L.Bean is known more for preppy rustic wear and a generous return policy, guns seem like a relatively obscure item for the brand. However, out of the company’s 37 stores, only the flagship location in Freeport, Maine, is licensed to sell firearms, CNN Money reported.

This week, Dick’s Sporting Goods, Walmart and Kroger all announced that they would change their policies and up the age limit for buying guns to 21.

Since the 19-year-old gunman entered Marjory Stoneman Douglas High School and murdered 17 people and injured 15 others, there has been pressure on lawmakers to raise the age limit for purchasing a gun. Under current law, the age restrictions are set at 18 years old for long guns and 21 for handguns.

Such a change has gained bipartisan support as well as praise by President Trump, but pro-gun groups argue it would be unnecessary discrimination shooters between
