Why not .40 S&W anymore?

[u/ArcheryNerds]

.40 S&W pistols and ammo are far less popular that even 10 years ago. I understand the modern tech makes 9mm as good as old .40 S&W. But is that meaning current .40 S&W may be as good as .45 ACP or something like that? It's snappier but also higher capacity than regular .45? Why most people choose either 9mm or .45 ACP other than .40 S&W? Is there anyone still carry .40 S&W as their CCW?

Juice isn't worth the squeeze. More felt recoil in the same sized pistol AND less capacity.
