There's been guys not stopped by 12 ga slugs, ya know. I dont care how long you've carried the .45, it's easily proven to be inferior to the 223, as far as typical .45 ammo goes, anyway, out of a pistol barrel. I'd be happy to prove it on people, if you can find some volunteers, but hogs, deer, cattle, etc, all prove me correct, and you wrong. The fact that you don't like to be proven wrong doesn't change anything. It just marks you as irrational. Most sensible people are happy to move up to better gear/tactics. The stupid hate change of any sort.
