That is the most illogical contribution to an argument I have ever seen in my life.
You own a lot of .40s or something? It's just one man's opinion... and he's definitely right to some degree. The .40 S+W is the cartridge that almost nobody asked for and somehow it got popular, despite the fact that it doesn't do anything especially well.
I sold all of mine a year or so ago and don't miss them at all. Maybe someday I'll buy another but I'm not in a rush.
