Maybe having the most popular caliber weapon isn't the ideal after all

I've been told to buy handguns with common ammo, like 9mm, (or even 22lr) incase there an apocalypse, economic collapse, world ending, whatever (I carry .380) and now I'm seeing there's a shortage of the especially popular ammo. Thought it was an interesting subject as I know people who are looking for 9mm and can't find any. Maybe if we got to the point of scavenging it might be good to have via /r/CCW https://ift.tt/2Uc2nlq
