Nothing wrong with the .40 S&W for a defensive weapon but it’s lost popularity for real reasons.
Yes - cost.
That and bearded skinny jean-clad man boys don't want to feel like the pussies they are so they cling to the FBI's direction.
So by the same “logic” were you a pussy that bought a .40 when the FBI went from a 9mm to a 10mm and then to a .40 S&W (short and weak;) before going back to a 9mm?
Again nothing at all wrong with the .40 S&W but you could look at a .40 S&W being to the 10mm what a .380 ACP is to a 9x19mm. No mag capacity gain, same bore diameter and unless shooting a very small gun no benefit and (theoretically at least) less effective.
There’s real reasons why it’s less popular today but that doesn’t make it a bad cartridge.
That’s my take. It obviously doesn’t make me right. All of my comments are meant in good spirited fun. Arguments about killing power around a campfire no doubt go back to the Stone Age and the best spear design for killing a T-Rex.
