That was the farthest thing from my mind when I started this thread. I have never owned a 40 and just wanted to learn a little about that caliber.
But, as we all know, chit happens!
Charlie,
Your original question of why not 40 was answered, for me anyway. While there seems to be some debate of the merits of the different calibers, there were some nuggets in this thread. The 40 S&W will cost more to shoot and has more recoil than a 9mm. I would say that the one extra round would/could be negligible. The fact that there was 40 S&W to be had during the ammo shortage means you could have shot more.
I have added getting a 40 S&W pistol to the list of weapons to buy. It may not be next on the list, but may go in the number two slot.
