someone please explain the 9mm ammo shortage

can someone explain a good reason as to why there is NO 9mm ammo to be found anywhere?

did aliens come down from space and steal it all then blow up every piece of 9mm ammo machinery in existence?

I see NO reason any ammo manufacturer couldn't flood the market with 9mm ammo if they wanted to and I also see no reason why they would purposely not have ammo for sale to meet customer demands because they lose out on making that money.

with 9mm being THE most common ammo out there is every bullet made going straight to police and military sources and nothing for civilians?

I just don't get it, any product in such high demand is a fortune waiting to be made by anyone willing to do what it takes to manufacture the product people want so whats the problem?

as far as I know there isn't a shortage of materials to make all the components so is Obama confiscating all the 9mm ammo that hits the market?

do ammunition manufacturers don't remember how to make 9mm ammo or maybe the one and only 9mm ammo making machine is broken and the parts for it are in north korea? yea that must be it.

seriously I could see a temporary ammo shortage, they happen all the time but after a few months they double the output of ammo and all the shelves are once again full of ammo but not this time so whats so different now?
