They all essentially suck until you get to somewhere around 200-250 grains at 1500+ fps.
The reality of that finally trumping all the hype, the world of handgun users have figured out that they might as well use 9mm because the advent of civilian defensive 9mm ammunition that actually is good for something leveled the playing field, FMJ TC ain't so bad after all, ball practice ammo is still dirt cheap, they don't kick as much, and hold more. Kind of a "no brainer" for anyone or any organization needing an effective sidearm.
I've always liked the .45 ACP and the 1911, maybe I read too much Col. Cooper when I was a kid. So I made that my IDPA caliber of choice, and have always counted on it for SD. Later on that decision saved my life, or at least I believe 100% that it did, and belief makes all the difference sometimes.
