I tried to buy a gun at Walmart twice, and roadblocks left me empty-handed both times The availability of guns at Walmart has become a hotly debated issue in the wake of two deadly shootings at its stores that killed 24 people. More than 128,000 people have signed a petition urging Walmart to stop selling guns and take a stronger stance against firearms since the shootings at stores in El Paso, Texas, and Southaven, Mississippi. But the company has said it has no plans to stop selling them.
