RE: .45 acp vs 9mm
Oh boy, another .45ACP vs 9x19 post!
Everybody KNOWS that only a sissy quitter will stop after being shot, even multiple time with a 9x19, but a hit to the little finger with a .45 ACP will pick up,a 300 pound man and throw him to the ground.
With modern designed, expanding bullets, both the 9x19 and .45 ACP are fine self defense cartridges. I happily trust my life to both.
