it goes without debating that they should purchase a 9mm

As a long time shooting instructor, I tell my students that if you go into a gun store to buy a gun, and the person behind the counter says "this is what you want", turn around and walk out. They don't know what you want because they haven't asked a lot of questions that go into finding the right gun.

Having said that, 9mm is a certainly a good option for a lot of people.

Agreed, the author did mention that 9mm was the cheapest ammo for EDC, something a first time gun buyer may feel is important.

I think panic buyers like these will just put their newly purchased handgun in storage with the stockpile of TP they bought.
