Re: .45 vs. .357
DeltaII5,
That is why I posted the comparison of rounds, To show that while the sig round comes close to mag ballistics, it doesn't quite get there, and in reality the ballistics of the .40 in 155gr trim might be a better self defense round. heavier, larger pill that has the same capacity in the gun as the SIG round. (since the SIG round is based on the .40)
For the best of both worlds in a 9mm framed gun (capacity/power) there is nothing wrong with the .40S&W
That being said, if you jump to the .45, you not only have a heavier round, but you also step up in diameter...
There must be a reason that the military (at least SOCOM) is heading back to .45
As far as I'm concerned the SIG round is an answer to a problem that doesn't exist. It doesn't really offer anything unique except it's penetration capabilities, which may be counterproductive in a personal defense situation.
