If you shoot, have some backlog of ammo and components. I try to go for 2 years worth. If something really bad happened, I would stop competing and have enough ammo for a LONG time.
The only firearms I could see myself wanting at this point are hunting shotguns or boltguns.
That said, yes, there are going to be a number of people that panic buy. There is a new 4 year window of people who could not buy firearms during the previous panic that are now. I have a local 21 year old acquaintance that is working a 2nd job, while going to college, and all of the money he makes ($100/week) off of it is going to guns and ammo. I still get an inquiry weekly form some other acquaintance wanting to buy 1 or 2 pistols and an AR or a shotgun for the impending zombieness or some other thing that they are not sure how to articulate. I typically have fun with it..."how much food and water do you have...none? No need for guns, you won't make it a week."
