I have never had a problem getting ammo. Wal Mart even carried it before all the panic ensued. Palmetto State Armory was selling Hornady 110 V Max for $9.99 a box for quite a while so I was buying 100 rounds at a time until I have acquired about 600 factory rounds and I reload so I always have brass around to experiment with.
These are the mags I use and have never had a problem with them. They are about the only thing Midway has in stock right now. Bought a couple last week and had them in a few days.
