Sacrifice power compared to the .45 ACP? COR-BON 125GR JHP 1425 FPS @564 FTLBS! Very fast, accurate and hard hitting round. .45 ACP is still a very good round but is very different from this. "Move over Rover" My SIG P-229R 357 SIG (26 ROUNDS AT 15 YARDS) All of my Glocks and Sigs perform very well in this caliber! YahtzeeI have the same complaints about .357 SIG as I do about other intermediate handgun calibers. You are either going to sacrifice power compared to .45 or sacrifice capacity compared to 9mm. Why? Because it is new and it will make you cool. Until the next new fad hits.
However, the exception would be for the sake of a drop in barrel for those that are already a fans of .40S&W.
new jersey staties carry the g31 as well, for the fact it will penetrate car doors, windows, and windshields while retaining knock down power. I'd recommend always using speer gold dots as carry ammo since they're bonded.
On a side note, its always fun to have friends who shoot 40's to take a few shots with the 357, they generally are scared.
