It also may be that many people have double or triple ordered. Then they'll only buy the first one that comes in. The rest of the perceived backlog will just evaporate.
There are gun shops that still have some ammo. Thursday drove over on the east side of town. I'd been seeing a gun store along the way called "One Shot". I saw an open parking space so I pulled in. Lots of ammo. And they were very proud of it! I saw 2 boxes of premium 12 gauge for $22.59 each! There was plenty of 22 caliber ammo, but the 100 round boxes were $13 each. For 22 rimfire. And sufficient supplys of 7.62x39 but a about $1 a shot. Too rich for my blood. So I was rude and impolite as always and evesdropped on a few conversations. Clearly newbies, looking to buy new guns at list price. And the helpful sales guys guaranteed the buyers they'd throw in a box of appropriate ammo!
I wonder what those gun shops will do if they don't get resupplied soon. I'm guessing with no guns to sell and little if any ammo, they'll close up shop or only open on Saturdays. Why pay high labor costs?
