Visited Walmart sporting goods lately? In my area just outside of Dallas, there is less ammo, and depending how far from the metroplex you are there maybe less guns.
They have quietly clearanced their supplies of pistol caliber, and .223/5.56 ammo. And some within 35 miles of me have completely stopped selling rifles and shotguns.
And the last Walmart that sold pistols (Alaska) has stopped selling them entirely.
