Not to sure about that , the local W-mart is still selling pistol ammo a few calibers they had sold out... this 09-07-19 afternoon.......
While supplies last. They’ll stop when inventory runs out is their plan.
They said they will sell what they have, but will not replenish handgun or “assault weapon” ammo.
I just helped Walmart lower their inventory of handgun ammo yesterday. Now when the weather cools down I will expend it downrange.
