Target is "respectfully" requesting that shoppers not bring guns into their stores.
"Our approach has always been to follow local laws, and of course, we will continue to do so," the notice says. "But starting today we will also respectfully request that guests not bring firearms to Target – even in communities where it is permitted by law.
"We've listened carefully to the nuances of this debate and respect the protected rights of everyone involved. In return, we are asking for help in fulfilling our goal to create an atmosphere that is safe and inviting for our guests and team members."
The retailer says guns in the store are "at odds" with the family atmosphere it champions.
A month ago, the group Moms Demand Action for Gun Sense in America launched a petition asking the company to prevent customers from carrying firearms in Target stores.
