All I can say is what I've observed, and here it is:

I see a ton of 40 ammo sitting on store shelves nearly everywhere I go. Back during the last ammo "scare", 40 was the only ammo readily available around where I live.

I see a ton of used 40 semi auto pistols filling up gun store shelves.

Does this mean anything? Who knows, it's just what I've seen.


Now...personally, I have zero interest in 40. I've shot them, I do like the round. There's zero reason for me to list my "reasons", I just personally don't have a need for one.
