I was in academy 4 days ago, and the gun and ammo section looked like a rock concert. 5.56 and 223 were gone, same with 308, 7.62x39, 9mm, 45acp, and 40s&w. There were a couple boxes each of 380, 10mm, and 5.45x39. This store usually has a total of 40,000 rounds of the above mentioned rifle calibers total. Stocks of ammo that is usually only chambered in bolt actions, lever guns, and revolvers looked a little less than normal, except for 30-30 which was gone, but they normally didn't stock that to deep anyway.
AR and AK mags were gone, same with glock and sig mags. They normally didn't have much else in stock. All the centerfire semiauto rifles were gone, pistol supplies looked good, except for glocks were sold out, right down to the display guns.
Friday morning at srt training, the srt commander told me to get 3000 rounds each of 223 and 40s&w, all our normal sources were sold out, and wouldn't even guess as to when they may be able to fill that type of order. I sent for a quote through a distributor who only sells ammo to agencies, but haven't heard back.
