If you're seeing product on the shelves, then that's the stuff they ordered ahead of time and stocked up.
I checked the websites of 3 different distributors and found that between the three of them, they had just 4 AR's, No Springfield M1A's, no PTR's, low supply of Glocks (mostly .45 GAP), 3 CZ-75's and not very many [less than 30] 1911's.
These distributors usually have 30-50 of most models and now we're seeing zero. This fits what other FFLs are saying -- the high demand is draining out the supply chain.
